I say go for the desktop for grunty work and pick up an older thinkpad for the mobile use case or just remote in with your macbook. I have a T580 (last of the dual batteries, infinite battery life baby), works an absolute treat on linux and next best build quality to a macbook but with a repair manual and massive upgradeability.
Thinkpads have long had first tier linux support, in fact many models have shipped with linux for at least a decade (?), checking that is a really good way to be sure, but you’re going to be fine with W, P, T, X lines, many enthusiasts make light work. They were deployed (might still be) to Red Hat kernel devs for a long time, which helps things along. Fingerprint drivers tend to be proprietary and hit or miss, but passwords work.
Honestly learning to install linux yourself, and configure it to your liking, is actually, imo, a really important path to learning and you’re likely doing yourself a disservice avoiding it. It’s part of the avoidance of vendor lock in you want. Installation is surprisingly easy now, start with something simple, Mint is often recommended these days, find a decent, recent, youtube and you’ll probably be up and running in an hour. Find the apps you need for your workflow (which will take considerably longer). Get familiar with the terminal. Best thing you can do after that is burn it down and install a new distro, leaving any mistakes behind, keeping your list of apps. Arch if you want to get really deep into it, or Fedora / Bazzite are good choices and very stable. Best of luck.
