Most laptops will be more or less fully compatible with linux I think. Though a few niche features like finger print or key card readers might be a hassle to get working. To me, the most important thing is the keyboard since some manufacturers forgo the end of/start of line buttons, for instance.
My main reason to use arch is the exceptionnally complete and useful arch wiki. Though many pages are useful for other distros as well. With the archlinux and package install guides, it’s just a matter of time (and study!) until you know how to get around.
