x86 Thinkpads + Fedora work great. Hardware support out the box is almost perfect (I would say perfect because I don’t recall anything not working, but I may be missing something). In fact, Thinkpads used to have Fedora as an OS option, which is why I think the support is so good.
Outside that maybe something like system 76. They advertise 14h for one of their models.
x86 Thinkpads is what I am gravitating towards as well.
Regarding system76 I have heard really good things about their workstations but not about laptops. Have you used them? I recommend PopOS to anyone getting started with linux as the first distro though.
I have not used their laptops. You’ll find the usual complaints about their fit and finish on the web, mostly because they are rebranded cleo’s. But I think everything else considered they get positive reviews outside of that.
