The problem with Mac hardware is that it's ARM and vertically integrated with everything Apple. Not all hardware is supported by Linux because Apple won't write any linux drivers and everything is reverse engineered. You're better off buying something non-Apple which linux properly supports.
If power consumption is an issue for you get, a R9 7950X consumes as much and at times less power than an M1/M2 (I think even M3). Check out GamerNexus's charts. IINM AMD in W/Ghz performs better than Intel across the board.
No idea where you are, but you can get a small factor PC from one of the vendors that preload linux, or configure a small form factor PC of your liking for cheap and put linux on it. You'll get more out of your money for the same or better performance with about the same energy consumption (or a bit more).
Somebody I know who happens to live in Hungary got himself this cheap beauty. They deliver all over Europe, but if you live elsewhere on this planet, there probably is something similar like this out there.
