Switch Pro Controllers are a bit spendy, but once you tape mod them to reduce D-pad mishits, they're as good as (first-party, non-counterfeit) Wii Classic Controllers ever were - I always favored those for Super Metroid speedrunning, and happily used their newer counterparts for the same purpose until my arthritis got to the point where it's no longer comfortable to speedrun with any controller. In particular, I've found Switch Pro Controllers to work well with the Raspberry Pi 4's onboard Bluetooth. So that might be a workable option, if you don't mind spending a little more - that said, I've had the older of mine for something like five years now, and it's stood up very nicely so far.
