Obsidian, notesnook. There a few lemmy groups that are pretty helpful with anti google / Microsoft questions.

I've tried Joplin and it has been a pretty good Evernote replacement. You use your own cloud storage, like onedrive, to store your notes, so you don't have to worry about storage restrictions like what happened to Evernote

Definitely check out notion, it should be absolutely perfect for your use case.

But if privacy becomes a key requirement, you can try obsidian.
