A lot of people here are recommending linux first laptops like tuxedo and system76 but if they are too expensive there’s also dell and lenovo which are linux-second vendors. Every dell laptop I’ve used has worked great with linux and are reasonably repairable. The only things to watch out for are gimicky features like fingerprint readers or anything that would need custom firmware, and super slim laptops (for repairability and the potential for weirder parts on the inside) but even for weird hardware like fingerprint sensors, both dell and lenovo have been working towards supporting them on linux as well.
