Keyboard & mouse user here. To lessen the pain, I moved to gyro-based gaming. I think 8bitdo has those. I specifically use the Switch joycons. I recommend you just get yourself a good BT dongle.

Me too. My weapon of choice is the Dualsense. Lots of great things about it in addition to gyro controls: as of late last year you can pair 4 devices with it. I have one Dualsense and roam between PS5, Bazzite desktop and Steam Deck seamlessly.
