Which Linux distro „just works“?

Ubuntu and it's official flavors, plus Mint, Pop_OS and Elementary all work out-of-the-box on Lenovo ThinkPad, Acer Aspire and Dell Inspiron notebooks, plus JBL Bluetooth speakers and headsets, plus HP/Brother wireless printer/scanner.

I know because I tested and installed them on my own devices and my family devices.

Ah! We also have a Canon Pixma USB printer/scanner and it works, but we don't use it anymore.

After a long time Fedora and Ubuntu user I recently switched to Pop!_OS (Ubuntu based) and really like it. The 'tiling windows' GUI is very neat (I previously used i3). I run it on 3 of my Lenovo boxes: an ancient T420 Thinkpad, a new P15e and a Thinkcentre desktop (not sure what model). All work with no issues.

I think it's more a question of the hardware setup you have. On physical machines, I have had no problems* with Ubuntu when buying Lenovo / Dell machines that say they are linux compatible.

*aside from some power and memory management problems that I think are universal

Linux Mint. https://linuxmint.com/download.php

I've had good luck with Fedora, especially in the last 5 or so years.
