I’m in a similar situation atm and have also been looking at Thinkpad x13 as well as x390 and older Dell XPS models. I’m a bit afraid that 8gb of RAM might be not enough in the future (afaik most of these have soldered RAM) but so far I did not run into problems with 8gb on my current laptop. Generally Thinkpads and XPS have very good Linux compatibility from what I heard.
ARM and Intel should both work well, I think (this might change for newer computers in the future since Intel let go a lot of their Linux devs in 2025 iirc).
