Fedora is probably the most
mature immutable desktop distro right now, both Silverblue (Gnome) and Kinoite (KDE). I use Kinoite on my Thinkpad x270 and it's been perfect so far.
Ubuntu will release its own version, Ubuntu Core Desktop, “soon” (got delayed earlier this year)
Another interesting one is Bazzite. Inspired by the Steam Deck OS but runs on Fedora (instead of the Steam Deck's Arch) with all the possible Nvidia, AMD, and other gaming enhancements enabled https://github.com/ublue-os/bazzite/

Don't forget the swaywm variant.
