I use Joplin too. You can use it on multiple devices and store your notebook on Nextcloud or Dropbox as excepted files that are decrypted on your device.

My requirement was to be able to write notes and also make checklists that can be checked and unchecked for use with grocery lists, and Joplin is awesome for that.

Joplin looks unpolished and Nextcloud sync option is often clumsy.
