Fedora 40/Wayland worked beautifully out-of-the-box with buttery smooth DE animations which unfortunately started flickering after installing NVidia's proprietary drivers which should be fixed with explicit sync [1] in NVidia's latest 560 drivers which is now available in KDE Plasma 6.1 update, hopefully it'll be available for Gnome in a system update soon - looking forward to running Wayland again.

Considered Pop!_OS but they're running an older version of Ubuntu and are in the middle of transitioning to their new Rust Cosmic Desktop which I figured would be immature at launch.
I ended up going with Fedora as IMO it was the more bleeding edge with new software, e.g. Wayland by default and their new Atomic Desktops look like they could be the future.
Previously the laptop had Windows 10 on it and there were no Bluetooth or reboot issues. Unfortunately, Windows 11 doesn't work on it and 10 is rapidly approaching EoL.
The machine has previously had Ubuntu on it, but that was a few years ago. Ubuntu didn't have any problems so either it's Fedora-specific or kernel or driver changes since then are the root cause.
