Just a small update.
I still haven’t fond what I’m looking for.
I am not playing a lot of music on PC but I am still using Audacious.
It’s the closest to foobar2000 simplicity and features I found.
But is still lacking many of its features.
Even tagging files is hardly possible on Audacious.
Apparently DeaDBeeF could be nice but I think I could not easily install it on Raspberry Pi, where I wanted to test it and didn’t find it in my old Debian 10 PC apt, either.
I should install manually but am so lazy, finding a software audio player is not high in my priority list.
