Self-hosting

For a hobby of mine, there's an outdated lore wiki on Fandom. I dislike Fandom and would like to host an alternative. It's supposed to be accessible to all kinds of people.

I started with mediawiki as that's what Fandom and Wikipedia are using, so people would be familiar with page structures at least and maybe the editor.

It turned out to be a bit of a pain though. It only has unofficial container images, the documentation is outdated and (what I consider as) core functionality like WYSIWYG editor or simple infoboxes has to be added by extensions or templates. I'm in the process of setting it all up and wondering if it's worth it (and if I want to maintain it). There's so many wiki projects it's hard to keep track, what are y'all using for stuff that's used by larger communities and simple to use with close-to-default settings?
