I built a similar tool you are describing. A quick demo and a technical post is here: https://notespub.com/. However, truth be told, I migrated off Notes to Emacs Org-mode recently and didn't finish the project for GA. If it helps, I do plan to release it on Github soon-ish.

If you are willing to go the extra mile, it is not that difficult to export Notes with media files from Sqlite and templatize them, and I am happy to help.
