Have a p14s (older gen) and it runs very well on linux. Im running fedora which lenovo sells prepackaged so you get firmware updates and bios updates through rpm. I would say any linux Thinkpad would be a solid choice. I would just suggest getting one without soldered ram so you can upgrade or repair. Also check the panel brightness too because my display is shit.

Genocide as a Service

I have the ASUS USB-BT500 and it officially supports linux and works very well. Buy that

Having just done this for whatsapp and discord, its a pain in the ass but nice once it is setup.
