Thinkpad X1 Carbon

I am strongly considering picking up a recent gen X1 Carbon. I really the like the idea of the device, having cellular data, working fingerprint reader and maybe even using it with an eGPU for some gaming. How possible is all of this on Linux? UPDATE: I managed to find a 9th Gen Carbon with LTE, I can't wait it for it to get here. Arch Wiki indicates everything should work.
