Looks like you got bokeh problems because of EFCS. Try to turn it off when using fast shutter speeds and large apertures, and the bokeh balls won't look like half moons.
I know, I often forget I have EFCS on
Sony needs to allow better automatic management of the shutter options so that I can set a rule.

Can you break down for me what you’re seeing in those photos to indicate that?

I made it part of the My Menu setup on my A7R3. Not sure if the camera you have allows for that, but I find I put a lot of things in there that helps a bunch.

Yes, the out-of-focus blur discs are "cut in half" with a brighter top part. This is because of the large difference between sensor readout speed (line per line) and the speed of the second curtain mechanical shutter. With ~f/2 (sometimes f/2.8) and faster lenses, you should avoid EFCS when shooting wide open and faster shutter speeds than ~1/500-1/1000 second if you want the bokeh unaffected.
I often forget it’s on too since it barely ever bother me, and the sound is a lot more pleasing The only thing that happens but is so hard to provoke, is at very fast shutter speeds sometimes a huge shadow, like someone applied a graduated filter.
