A lot of players and local venues prefer PS4, PS5 and PC for fighting games. If you have licensed PS4/PS5 arcade stick it should work on all three of these platforms. Unlicensed ones might not work with PS5 games. Switch is mostly just for melee.
That being said game key-cards seem largely inferior to physical versions on other platforms even if you likely have to patch most games these days anyways.
Bought Baldurs gate: Dark alliance from g.o.g and playing that. A bit expensive for its age and its a direct port but at least no need to emulate it.
