Have you considered tiddlywiki? You can selfhost, or use one of a couple of services. I know of https://tiddlyhost.com/
Also you could consider anytype. It's cool, and I like what they're going for. I don't like their weird pretending to be open source license, but it's still pretty cool software. https://anytype.io
Edit: for my personal stuff, I use a combination of logseq, and tiddlywiki, the latter moreso for game development. I landed on anytype at work because it's simple, and my boss, nor anyone else cares about a license, and it just works.
Thanks for pointing that out! I was looking for an original source, but the articles Wikipedia uses as sources are from a defunct journaling site. However, you can see at least one of the original articles through the wayback machine.
