You won't find anything like the Macbook Air M1 in build quality, display, and battery life

Thinkpad X13s and T14s (both with Snapdragon) are the best closest alternative.

The M1 Air display being 2560x1600, it isn't that high of a bar to cross.

Surface Pro are 2880x1920, Asus’ pz13 series will be in the same ballpark. Getting Linux on them will be a bit more of a PITA, but you get the touchscreen and form factor to balance. Build quality will be basically on par with Apple, battery life should be taking a more serious hit (linux + smaller battery from the start)
