I have the same issue with organizing my notes. On the mac, I have recently started using agenda (https://www.agenda.com/) and am really liking it. You can easily link notes to dates, events, and other notes. You can export notes and sync through iCloud or Dropbox.
The free version already gives a lot of useful functionality and they have an interesting payment model in which you unlock all current features (and updates over the next year) with a single payment. Hence you could use it as a subscription or simply pay once if the new features are not yet worth it to you.
