Fedora is indeed a pretty solid option its very stable and you are still up to date when it comes to packages.
One distro that I personally use and I'm going to shill is void. Its bleeding edge but its surprisingly stable. If you don't mind reading documentation and researching similarly to arch you shouldn't have a problem (since you are accustomed to endeavourOS).
Honestly, i think if people did videos here and there mentioning lemmy and the info they found in here (similarly like how reddit is shilled sometimes) there would be a bigger growth in user count in the Lemmy instances over time
The oddlama installer looks interesting, I might personally check it out later 👍
