Not really no. The differences between distros are essentially rooted in philosophical beliefs defended by near religious zealotry. Entire identies are defined around the differences between distros.
A bit of an exaggeration, but well...pretty much that.
These differences mostly come down to package manager variations, which should be one of the main considerations when picking out a distro in the first place. My personal advice is to use Arch/Manjaro with pacman, and avoid all snaps/flatpaks. The AUR is designed for people to integrate these apps like Spotify and Bitwig into the proper locations, instead of snaps and flatpaks making their own folders and such.
See File System Hierarchy Standard[0], or `man hier`.
As a very casual Linux user (macOS is my daily driver), are there any efforts to solve these "death by 1,000 cuts" arbitrary (I assume) differences?
