This is how M+KB natives feel on controller.
You will get used to it if you keep playing, but it might never feel natural unless you use it exclusively for a while.
I’m a trackball + keyboard user so mouse + kb and controller both feel sort of almost right but somehow wrong to me
Also some genres lend themselves better to one or the other. I prefer controller for platformers and fighters, but prefer TB + KB for almost everything else

if you have a spare SD card you can also play game backups off it, and there are lots of other fun things to try like homebrew games and emulation
I would never consider a smartwatch that is locked to one ecosystem, so Pixel watches have no appeal
