Just use obsidian and the github repo addon so all your notes are not only backed up in a private repo but also with Git revision.

Edit: reading your requirements I’m sure above satisfy them except probably ‘programming notebook’, unless there’s an obsidian addon for that.

Great idea! After a quick search, there's some plugins[0][1] that could work for my use case!

Awesome, glad to help, and thanks for sharing those addons, didn’t know about them!
