idk man, i use fedora silverblue.
fedora atomic os variants are really good.
but i use my own ostree image on github. its on top of fedora's bootc image.

install apps as flatpak.
or create a distrobox and install it inside them.
or use appimages.
for example my whole dev environment is inside a distrobox.
i have another separate distrobox for my bitcoin node and stuff.
and you can actually have each distrobox use their own isolated home folder, keeping things organized and easier to clean.

there are really cool GUI apps like:
DistroShelf
BoxBuddy
Bottles
Gear Lever
etc.

lets you manage things without opening a terminal

for distrobox management, i would only suggest DistroShelf, but BoxBuddy has better UX while exporting app launchers from the distrobox.
