I highly recommend Framework laptops for Linux. I have not used the Framework 16, but I can attest that Linux support for the Framework 13 (intel 11th & 12th gen) is excellent. I have used Fedora on the Intel 11th gen and Intel 12th gen, everything worked immediately on a fresh install without any workarounds or issues. Other distros might require a few package installs, but Fedora, Ubuntu, and Ubuntu derivatives should work out-of-the-box without any additional configuration. The Arch Wiki article for the Framework covers pretty much everything you might need to know to have an optimized Linux experience with any distro.
Aside from Framework's excellent Linux support, I really have to stress how cool and unique it is as a laptop for developers and tinkerers. This thing is literally designed to be opened up, repaired, and modded. All of the internal components are clearly labeled and easily accessible, there's even a little spot inside the laptop chassis just for spare screws in case a screw ever gets lost! Another awesome obscure feature of this laptop is the ability to use a Storage Expansion Card for dual booting. I just plug in the expansion card to boot into Windows, then unplug it and I'm back in Linux. It is absolute bliss compared to Windows and Linux sharing a bootloader.
I know I'm rambling, but I really could keep going on and on about Frameworks. They truly are unlike any other laptop, in all the right ways.
