Use Linux if you don't need any mainstream applications, nor reliable sleep/wake, audio, wifi, etc.
Otherwise, get the whatever's the cheapest MacBook Air or Mac Mini and move on with your life.

I use Linux on my desktop in my basement as that is the "fun" computer meant for entertainment and some coding. I have a Macbook for a lot of "serious" work because if I am out meeting people I need the software to work the first time I open it and not waste time troubleshooting.
Side note on the comment about reliable sleep/wake...Linux is very good at this, just look at the Steam Deck.
You're not wrong that a cheap mac is an easier solution, but with its own downsides.
