I ended up landing on https://silverbullet.md https://silverbullet.md. It checks a lot of boxes for me, - self hosted - works offline (mostly) - "just md" BUT - scriptable or extendable by lua, rendered in page, eg `${1 + 1}` outputs `2`, but you can do a lot more, such as query pages and tags with a LINQ type query interface.
