It was believed that if a third party bought Sony then rights would revert automatically to Disney but I've heard a lot of contradictory information about the contracts flourishing out there so even that's not a guarantee.
I am also quite sure, or at least would be highly surprised if the opposite is the case, that No Way Home will be the last MCU/Sony collaboration. After this, Sony will go its own way. They might do Tom Holland College Spider-Man movies but they will be standalone and not tied to MCU. Tom Holland has a contract with Sony after all, they sign his checks, and they're funding his UNCHARTED movie, so he can't escape the street gang he's currently part of.
I don't see much or any interest for Sony to keep Spider-Man in the MCU after ENDGAME because Iron Man's gone, Chadwick Boseman is dead and there's not much existing attraction to tie Tom Holland Spider-Man with. It'll be a while before FF and X-Men get revived in any form of crossover state, and they obviously don't care for Disney Plus streaming appearances since that gives Disney more leverage.
