I recommend you try Gentoo and DWM. You don’t have to use this setup forever, but at least try setting it up. Installing Gentoo, patching DWM and st, etc. is fun and it’s an interesting experience. If you want to use Wayland, check out dwl and the foot terminal emulator. Perhaps you’re actually gonna like Gentoo and stick with it, I think it’s a great distro. They also provide binaries for larger programs, so you don’t have to compile stuff like Firefox. But definitely try out custom kernels.
