There is a GitHub project called “Awesome-Linux-Software” (22.8k stars). It’s a curated list of FOSS Desktop software on Linux.
It was what convinced me to switch from MacOS to Linux (first Debian, now Manjaro) 2 years ago, because it showed me for the first time, that there is a nice Desktop app on Linux for pretty much EVERYTHING.
If you’d print the list, it’d be ~ 50 pages.

Fully agree, the software landscape on Linux is mind blowing.
