The new Ryzen mobile processors should be interesting. Their GPU drivers (while not of the best code quality) are in the mainline Linux kernel. So it all should just “work”
If you don't know enough about CPUs to even read reviews that compare the CPU to other CPUs, then you either don't need the extra IPC of Zen 3 (and you won't notice when you use your laptop day to day) or you just... don't care.
If you care, get a 5600U/5800U or H line and it will never affect you. The laptops these come in should be priced accordingly.
