Re: Z8 extremely unreliable/inconsistent AF in mildly low light

The exposure with no flash is extremely dark so motion blur should not be a problem.
I'm pretty confident part of your problem - certainly in the recent event comparison photos you posted - is double/delayed exposure trying to mix ambient with flash, where the two exposures approach eachother. I've shot 1/200 and can't get a sharp photo, but it's because I'm mixing ambient with strobe and the subject and I are both moving. In these instances I bump my ISO and switch to HSS and shoot 1/1000 or faster, with my strobe set to super low power like 1/64th or under, and the images are tack sharp. Z8, Godox lights (AD600 or AD300Pros). No banding across the frame at all. FWIW I *have seen banding* on my D810 in HSS at 1/320 or 1/500, but it disappears at shutter speeds faster than 1/500. So in moving to the Z8 I’ve just instinctually avoided anything slower than 1/1000 for HSS.
Not sure what FM is doing to mess up the links here, but copy and paste this to see Z8 in HSS, no banding, tack sharp eyes: https://imgur.com/a/d6sdRx1
