xfce is really not an important project IMHO, it's an interface from the 00's that doesn't have a clear usecase to me at all. It's a strictly worse version of KDE in my eyes. The only reason to use it seems to be if you're already used to it and don't want to have to change anything.
Yeah, it should! If it was a supported graphics card
The GT 710 relies on the nvidia-470 driver as the newest supported one. Anything newer and it just doesn't run
I switched when I made my notebook my daily driver, and so far it's been going well for ~6 months now.
But I swear to god, I miss bspwm and didn't find an adequate replacement
