If you invest a few bucks in a decent controller that can connect to android and PC then it opens up a ton of options to you.
I know Bitdo does some popular controllers that seem to be in that sweet spot of decent quality for a reasonable price but I've never tried any of them.
I have a Gamesir T4 pro, which gets recognised as an Xbox controller on PC so it's good for steam games and it has all the features that make it an ideal all-rounder in my experience. It comes with a controller mount so you can attach a smartphone to it as well but I've never used it.
Seconding this recommendation
