In general, I would recommend you look for something that has an Intel chipset and graphics card. Be careful with wireless cards. In general, only (some) Intel and Atheros have good quality drivers. This rules out most machines, sadly. Some Thinkpads and some Dells will be suitable, though. And from time to time, excellent models from other brands. Like Xiaomi Mi Air 12. There are other exotic options that also run really well on Linux, like some Rockchip ARM machines, but these are not powerful at all. I would also look into cooling, as some machines are a disaster. Thinkpads and Dells tend to be OK, but some specific models have had issues.
