Was about to mention this. 25y+ linux user here, we all had our ricing phase, where we'd customize our desktop and shell to oblivion. Now, I'm always on a as-vanilla-as-possible Ubuntu machine, or a Macbook with the same default wallpaper that came when I bought it.
The only thing I do to my new systems is installing oh-my-zsh, because that gives me a lot of goodies for basically zero configuration (I just use and learned the default presets to be "my own")
