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.
