120FPS or faster is very useful even if you don't need to shoot at 120 FPS.
When the global read-out speed becomes really fast, a lot of computational features will happen in full frame.
Sony introduced a feature called "composite RAW" with the A9III. Not sure what exactly that is for now, but it seems that it can be used with moving subjects.
It’s absolutely true, on a A7iii / A7iv body, while the body is capable of 10fps, if AF prio mode is used maybe you can only achieve 6fps because the camera delays shutter release until an af lock is achieved
Ditto for the A1, while the body is capable of 30fps, if AF prio mode is used maybe you can only achieve 20fps....
I assume this is pure speculation on your part because I have always used Focus Priority mode with the A1 and get 30fps nearly 100% of the time regardless of whether I am shooting a static subject or a small fast subject.
Similarly I have an a6700 and shoot that in Focus Priority mode at Hi (7fps) and it never seems to skip a frame. You can find links to sequences with both cameras in previous posts of mine.
It seems to depends on how hard the subject is for the camera to track, how fast the lens autofocus speed is and how bright the lens is. Admittedly its difficult to tell what the exact frame rate is on the A1, but on the A7iv its more obvious
I cannot comment on the a6700, which I have not used.
