a wiki is much better than google docs IMHO as the later quickly becomes an unmanageable dumpster fire. I like mediawiki a lot since most people are familiar with it from wikipedia and linking to yet-to-be-created pages encourages participation.
Agreed on the broad points. Personally I found simpler wiki systems to be worth it because you'll spend less time making stuff work and less time debugging because it's less complex. MediaWiki, at least from my experience with -pedia, the OpenStreetMap wiki, and others, is that it's complex and slows down to a crawl for hours~days if you bust the cache by making a change to a central template. DokuWiki runs smooth without needing to concern oneself with caches at all—but, of course, is less versatile if you have a 10'000-people organisation and need advanced features for managing all the information (we don't; it works great for us). I'm sure there are also other great options besides DokuWiki, especially if they use a markup language everyone already knows like Markdown instead of some custom syntax only used on your wiki. Another consideration: GitLab, Gitea, and friends iirc all didn't have page locking when I looked at those options ~2 years ago, so you overwrite each other's changes without noticing. Anyway, just some thoughts on implementation details. Wikis are definitely the way to go as compared to a set of documents on a drive!
