Basically lateral CA is variation in the "magnification" of the different colors of light and axial CA is a variation of each "wavelength" of light.
The former is visible at the edges and the latter anywhere in the frame (including center). Purple fringing is longitudinal/axial CA and also deals with wavelength discrepancy. The only difference is that it is visible on the focused area.
Lateral CA does not go away when stopping the lens down but it's easy to correct without significant IQ loss.
Longitudinal/axial CA goes away when stopping the lens down. Wide open, it's not easy to correct but can be masked in post.

I know it's hard to resist but we should not compare color aberration correction from lenses with different focal lengths.
Instead we should compare the FE 24/1.4 GM to other 24mm f/1.4 lenses. The FE 24/1.4 GM is well regarded because it actually does better than the competition in regards to CA and resolution while being compact for what it is.
Here is a high contrast sample showing axial CA on the metal chain: (front of plane of focus)
my personal threshold is if you have to post a 100% pic to see the problem, I usually don't care. I mean if you look at pixel level, there is sooo many things to nit pick on.
It is all about alternatives. I still kept my 24mm gm for years even though the fringing is so obvious in certain conditions. 35mm, there is the sigma f1.2 which does almost everything well in terms of IQ, thus the 35mm gm has to perform better than the 24mm gm for me. My bar for the 35mm is higher because of the sigma 35mm f1.2.

The Sigma 35/1.2 has indeed better axial CA correction if you compare it to the 24/1.4 GM but like I said, it's not really fair to compare them.
In the case of the new FE 35/1.4 GM, it's still a question mark for me, but from what I've seen so far, axial CA is visible in some images, although it seems to do better than most 35mm f/1.4 lenses available. Perhaps the Sigma 35/1.2 will still have better correction. Not sure.

I never loved the 35mm FE, to the point where I've used it maybe two total days and haven't touched it since. I love the CV 40 but wants something with AF between the 24GM and 55/85.
Should I order this sight unseen, or has the ship sailed in terms of pre-orders times and I should wait for reviews and folks to post their shots?
I remember the 24GM being hard to get for 6 months or more.

That will help.
Lateral CA happens outside the image center with high contrast structures, and doesn't go away when stopped down and can be in the focal plane. Longitudinal CA happens just before and after the focal point, being either green or purple, but is fixed by stopping down 2-3 stops on most lenses (like the GM 24 or Sigma 35/1.2). Both result from a lens' inability to focus wave lengths optimally, but look at the link to see how they differ.
Practically speaking, I recently purchased a ZF 28/2. Wide open at f2, if I focused on a nail from 2 feet away, just before and behind were purple and green around the nail. If it were an APO lens, we wouldn't see that (or much much less). By f4 on the ZF 28, the false color is gone/insignificant. However when I checked the lens at infinite, I saw lateral CA purple outlining on tree branches even at f8. It's an older lens now, but not that well corrected for either type of CA.

My quick, casual scan of reviews doesn't suggest much (maybe focus breathing, that's crazy multi-mm focus breathing on the GM... maybe it is a 40mm + lens up close?)The discussion in this thread points to "on axis" CA (purple fringing), like Fred called it, which I also have a feeling will behave similar to 24GM so not too well in demanding conditions (e.g. branches against heavy backlit sky).
This was and still is I guess my main gripe about 24GM, when I took it to the forest with harsh winter sun and trees/branches covering the whole top of the frame, the results were pretty disappointing (but then I'm not sure which lens would do significantly better, maybe the bigger Sigma 24).I was beginning to think I am alone about the 24mm gm issue with color fringing. Example of the 24mm gm below. It is really a significant issue so I am not sure why 24mm is so highly rated. It is a good lens but it is in no way perfect. I am beginning to feel the same way about the 35mm f1.4gm. I don't want to sell my 35mm f1.2 which honestly I have no complains about in Image quality. Sure there is some color fringing too but it is really quite low and below my threshold.

The sort of compromises you have to take to have a sharp and compact lens... to know for sure if the GM 35/1.4 meets your expectation, best to shoot with one. But likely you will have to keep your Sigma. Fringing is annoying for me for sure, but less so to me than the weight and size one has to take to suppress them at the current tech. I’m pretty sure all of the high-end Canikon RF and Z lenses will have no problem with this. You don’t mind the weight, those might be a better system, especially Nikon Z. Ignoring the weight and size, the two Nikon S 58/0.95 and 50/1.2 are very sharp and well corrected (remarkably so), even more than the Canon RF counterpart. Either that or you need to keep buying those very fast and big Sigma, though I always prefer first party offerings.

More out of curiosity than real consideration given it weighs 29.372 lbs and is taller than my camera backpack, but now that the Sigma 35 1.2 is plummeting / will plummet in value and like new copies can be found on B&S already below $1K, well below new GM + tax pricing, is there any respect in which the Sigma seems to outperform the GM at common apertures (from f/1.4, I know you get f/1.2 with Sigma...) based on early reviews?My quick, casual scan of reviews doesn't suggest much (maybe focus breathing, that's crazy multi-mm focus breathing on the GM... maybe it is a 40mm + lens up close?)

Longitudinal CA will go away on stopping down.
If you have already taken the photo, then lateral CA will usually go away if tick the me move CA box in Lightroom or equivalent.
There are typical colour signatures you can learn, and LaCA tends to seem like a sharper edge fringe.

Here's a practical advice on how to correct Longitudinal/axial CA in Lightroom:
1. Tick 'on' the corrections of chromatic aberrations and make sure you have right colors setup there - this of course does nothing to longitudinal/axial CA (but it usually corrects the lateral CA if there is any)
2. Take 'Adjustment brush' and paint with it on the areas where you have longitudinal/axial CA in the picture. Then hit hard with the 'Defringe' on the adjustment brush panel. This usually corrects some of the longitudinal fringing, sometimes almost all of it, though results vary.
I've been correcting some of the Batis 25 images when shooting wide open and Fred's example of GM fringing looks very very similar. Of course massive fringing cannot be totally corrected, but most of the time the irritating aspects (ie. bright non natural colors) can be reduced not to take attention in the image.

What a great discussion on the CA topic 
!
Can you help me and try to tell what kind of CA the fringing on the branches in the background is (f11, but focused close):
DSC05817 by Jan U, on Flickr
I chose this shot as it's not overexposed, which helps a bit I think.
In other shots I have from that forest, the sky is overblown, which makes the matter even worse, even though they're at f8 and the branches in the background are more or less in focus...

The peculiar thing about some of these recent modern optics is that some situations can really bring the worst in them, especially LoCA, though it can be only in some rare occasions. From lenstip, I see on axis, the GM has a tad more color error in focus, while out of focus, it’s about the same.Yes, "on axis" color error (purple fringing).Is this the kind that can be easily removed in post, or no?You can try a sharp violet cut filter like this https://www.ebay.com.au/itm/Optical-450nm-Long-Pass-Filter-Glass-UV-Cut-Filter-50mm-Square-/263633374813
I have a modded camera (430nm-690nm) which doesn't seem to suffer purple fringing, but I definitely see the other side (green fringing).I thought mirrorless cameras already cut out UV light?
Yes but they pass plenty of visible deep blue light which they display as violet/magenta.
