I tried Silverblue for a bit, it's quite neat but I found it annoying that I had to overlay Gnome Tweaks in order to configure the fonts used. I'm also not sure how I feel about Fedora filtering Flathub, it's easy enough to override and I'm sure they have a good reason for it and most applications are available, but still. Toolbox is a really nifty gadget to play around with, though.
Also tried the KDE Plasma alpha (beta?) of OpenSUSE MicroOS, it could use more love.
Kinoite may suit my tastes better, I'll give that a try sometime soon; I just hope that RPMFusion will update their setup instruction by then because the ones I tried didn't work properly.
