So far as I remember, the big advantage of the cr is the ability to do pixel-shift with the already higher resolution sensor. The cII has the higher ultimate frame rate, it doesn't fill up the buffer as quickly, and you can get full-width 4k out of it's video. Otherwise, they're the same camera, so, if none of that matters to you, then it really comes down to sensor resolution and what you're comfortable spending.
The A7CII also has more AF points than the A7CR, which gives it better coverage and should give at least a small advantage in autofocus. It also has slightly larger pixels, which should help with high ISO shooting.
On the size issue, I find the A7Cxx cameras significantly smaller than the A7RIV or A7RV for my handling and purposes.

As I suggested above big pixels don't really help with high ISO shooting if you downsize the files from the camera with small pixels to the same number of pixels as the camera with larger pixels.
I don't know that there is a "right" answer that's the same for everyone. For now, I'd likely go for the A7Rv over the A7CR - mechanical shutter, evf and rear panel, part of the consideration and I have several larger lenses, too.. (I have an A7Riv and A6700 and several lenses for both.) No immediate needs/plans for a new body at this time.
Size? Not asked/mentioned so far - what lenses are involved in all of this? I've tried the 28-200 on the A6700 to see how it feels. For me, the Tamron 28-200 or 28-75/2.8 might be the "size" point at which it doesn't make sense to trade away all the larger body enabled A7Rv features. OTOH, I like the A6700 and 70-350 for zoo walks, or as the "just in case" handy "wildlife" camera while doing landscapes.
I have found that in looking at camera bags, at times the A7Riv fit better in dslr bags compared to mirror-less bags when fitting a body and couple of lenses, especially compared to the A6700 and aps-c lenses.
Otoh, if looking to a smaller lens or a couple of smaller lenses, the A7CR might be nicely smaller and offer easier carry, etc.

I wish more people would make that point about the supposed advantage of “big pixels.”
To take one example, there’s arguably less noise per pixel from larger pixels. However, by the same token, the “grain” of the noise is smaller and therefore less visible with more, smaller pixels. (Not to mention the fact that the noise performance of modern sensor is generally quite good on virtually all cameras.)
(For those who may wonder, I’m in this forum to learn more about the Sony ecosystem as I consider a possible move to the brand. I only participate here when the issue is not brand-specific or when I have a Sony question. Otherwise I’m an official “Sony lurker.” ;-)
Dan,
Good to see you here. You should consider becoming a Sony Ambassador. Your work is quite impressive and they seem
like they can benefit from your talents. BTW, I ‘ve sometimes shoot eagles with your brother up here in the Pacific Northwest.

Bill Claff argued that "photosite size is not a factor in noise or diffraction as it applies to our photography." I find his argument convincing. For details see https://www.photonstophotos.net/GeneralTopics/Sensors_&_Raw/Resolution_Doesn't_Matter.htm
