I still haven’t had enough free time to fully dive in, but it seems to work with my test notes.

You’ll have the benefits of a Note app interface (like Apple Notes, Bear etc.), mix it with handwritten notes via GoodNotes (multiple folder levels) or Notability (auto-backup is limited to one folder level) that show up inside of Notebooks and in addition the powerful indexing of DevonThink.
