At a distance of 3.5m, a 65" screen is certainly better.
I would no longer buy the Sony A1 as long as Sony has not optimised its Android operating system. For me (and many other people), the TV produces an unannounced reset about every 2 days, then restarts with the SONY emblem and the Android light chain. Very unpleasant. Despite two firmware updates, the problem has still not been solved. Actually
Yes, Dolby Vision is supported.
Well, of course it also depends on the distance at this size of tv, and it also depends on the settings of the device, but also whether they are directly on the cable or via a tv box.
I could not say for sure. Yes, it has a 3.5mm audio out for headphones or subwoofer, plus even an optical output, but since the subwoofer you mention is WIRELESS and intended for BRAVIA TV's, I honestly cannot say. If you plan to connect with wires, as long as your Sub has an audio in connection (chinch or 3.5mm) you should be good to go. Hope this helps.
