tl;dr: Find a used T480s for like $500. Upgrade its RAM and replace its battery if you need. Install PopOS and Regolith PPA. You'll be a happy camper.

Librems looked pretty cool. I might get one next.
But I've been running my T480s since 2018 and it is still going strong, I don't imagine I'll replace it unless I drop it on hard ground... wait I've done that. or spill coffee on it... wait I did that too. Did I mention they were durable as heck?
For software:
I run PopOS for ubuntu-easy software and compatbility with a Regolith PPA because i3 window managers are amazing. Since its a thinkpad, you can swap out and replace most parts easily including the battery when it eventually wears out (literally takes <10 minutes).
