Pinball FX (the successor to Pinball FX3 just to be confusing I guess) on the Switch seems to be in a much better state than it was last time I tried it. It seems less buggy! Like there was a problem before where the audio on Star Trek the Next Generation sounded really off... Warble-y I think was the thought I had then? Also there was a problem on the update before this one where when attempting to play offline it would continually try to reconnect to the internet and it would just make it impossible to play offline.
Neither of those seems to be an issue now! I feel like it's better graphically than it was back when they first launched it as well. Also more of the tables from FX3 if not all of them are in there now.
You can just download them if you previously purchased them. They just added Bride of Pinbot also so yay!
