Your best option is framework IMO.

The 2.8k panels are overall inferior to Apple's across a number of metrics, but they have a higher pixel density than the Air 13, (and has the S-tier aspect ratio of 3:2).

The FW13 keyboard is objectively pretty decent but not perfect, and is much much better than any keyboard Apple has made in the last decade, could be personal preference but apple has been making some pretty bad keyboards for a while now.

Trackpad on FW13 is OK, no one even comes close to Apple, but it's pretty decent, nothing upsetting if you're comparing it to any non-apple trackpads.

Framework has excellent linux suppport, all hardware bells and whistles generally work out of the box on every Linux distro, but Fedora, Ubuntu, and Bazzite are officially supported by Framework they QA against all three and work with maintainers to resolve issues and you can be totally confident that everything will just work. (At least work as well as it would on Windows!)

The other two downsides relative to a macbook are build quality and support. Although the FW13 is pretty solid in practice, I have dropped mine dozens of times and throw it in my bag and treat it overall rough and it has take on some dings and scratches but everything still works. But the frame is not very rigid, it flexes in lots of places, and it just does not feel as nice and solid as a macbook. And support can be hit-or-miss, like with any small manufacturer.

I think you’re talking about Apple’s butterfly keyboards which were only around for 3-4 years of the last decade you’re talking about. Apple’s keyboards have been great for 5+ years now.
