Kavita
Kavita is a fast, feature rich, cross platform reading server. Built with the goal of being a full solution for all your reading needs. Setup your own server and share your reading collection with your friends and family.
I'm still working on Kavita, an open source, self hosted book/comic media server with a strong focus on metadata. Been in deep developing a custom annotation/highlight system for epubs.
Annotation ideas: https://github.com/Kareadita/Kavita/issues/3890 (since from research, seems there is a strong need for this)

When I started to track my finances I quickly ran into limitations with just a spreadsheet, and also didn't feel like any of the existing options fit my need. I agree that for most (all?) people this level of detailed tracking is probably too much, but it doesn't take that much time for me.
I ended up making my own app https://github.com/VMelnalksnis/Gnomeshade. I also felt similarly regarding accounts, so I split transactions into two parts - transfers and purchases. That allows to handle multiple currencies, and handle categorization separately from accounts. I haven't looked into suggestions like you mentioned, I went with trying to parse receipts for my most common purchases.
