Attributes are meant to be user facing, and are super useful for all the assorted info that you can use during autofill steps. I primarily use this to autofill card information with autotype.

Cryptomator checks all the requirements. It is a cross platform, GPL'd, encrypted overlay filesystem which you can put anything in, not just markdown docs. Just unlock it and point your notes app to it. Lock when done.
