I saw no one had replied to your question, so I thought I would jump in. I have both an X-T4 and the 56 1.2 (non APD) lens. I've never been disappointed in their performance.
But, I looked over some of the links you provided, and then ran some super-simple tests with my lens. ... and there is something odd going on... but not sure its missed focus.
Sorry I don't have photos attached, but I used my sleeping dog as a subject and shot at f/1.2. This was not eye tracking, obviously.
When I selected a center(ish) focus point and looked at the photos (on the camera, zoomed in) things looked sharp at the focus point.
When I selected a focus point out toward the 1/3 area, and did the same... things were slightly less sharp. And when I moved the focus point closer to the frame edge, even more so.
Sounds like filed curvature to me.
This is some very old and very ugly wallpaper shot with the 56 wide open not far from its close focus limit. Considering the ridiculously shallow DOF at this range, I'd say this thing is sporting a rather flat focal plane. And no, this wallpaper doesn't look especially sharp in real life either.
