An easier one stop shop alternative is just Notion. Recommend it for the reason of having an internal wiki/documentation. Probably one of the only real use cases for Notion, everything else (like personal note taking or time organization) is horrible on it.
This was actually my next suggestion when Obsidian got shot down. It's definitely a nice half way house between the two. Again it got dismissed albeit this time with no explanation, I assume because the request for feedback and suggestions wasn't actually anything of the sort but basically a pretend exercise on behalf of management to 'show we're listening'.
