I think I can live with heavy vignetting or focus breathing as I don't care too much for those but 2 things from lenstip review might affect overall picture quality imho:

Not deal breakers, but something to keep in mind I think.
The Canon has clearly more vignetting, half a stop more (if opticallimits is correct), look after 6:15 in Manny's video, too. Looks like the Sony is comparable to the Nikon, here.
Distortion is a bit higher (0.6% vs. 0.25% (Nikon) vs. 0.2% (Canon)), but nothing to be concerned about , imo. I think Sony went the Sigma route in trading size for distortion.
CAs look indeed well controlled. I expected the Nikon, due to its size, to be better: https://www.cameralabs.com/nikon-z-50mm-f1-2-s-review/2/
But that doesn't seem to be the case.
I like Manny but it’s seems pretty clear he had vignette control enabled on Sony (-2.9ev per lenstip) and Nikon (maybe?) but not Canon (-3.2ev per optical limits). Less than a half stop difference wouldn’t be the drastic difference shown in his examples - we don’t know his exposure either. Leave the technical reviews to the sites that repeat those types of tests frequently and influencer YouTube videos for entertainment.
