For what it’s worth, a YouTube review using a 105mm F/1.4 close up at F/1.4 the Eye AF focused on the eyelash instead of the iris and the eye was out of focus.
Maybe you could find a 85mm F/1.4 or 105mm F/1.4 for your review?
DIGLOYD: my first tests with the Nikon NIKKOR Z 24-70mm f/2.8 S show that the Z7 has a strong preference for eyelash and eyebrow focus, which suggests that Eye AF is a failure on the Nikon Z7. I tested at 70mm primarily.
I need to test the Z7 some more, but I am not hopeful. Between Eye AF on the Nikon Z7 and Eye AF on the Sony A7R III and Eye AF on the Panasonic S1R, I now have several hundred portraits with out of focus eyes, and I feel discouraged in wasting my time further. It all seems like one big lie shared by all the vendors. The emperor has sharp eyes—just look at those lashes!
If a camera cannot focus sharply on the iris of the eye at f/2.8, then it is a disaster at f/1.4, which has half the depth of field of f/2.8.
