I find Joplin perfect for my needs. Markdown, embedding images, links etc. I sync to my selfhosted nextcloud.

I like tags, I would like them to add a “directory tree” type of view to help sort “folders” (the thing they call “notebooks”) but only because I am more used to just filesystem type structured filing. But the notebooks and tagging idea works for me too.

I strictly use it for notes/note keeping, in particular “HOWTO’s” and specific topic notes. So I dont even do a great deal of markdown in my notes, but I love the ability to add screen captures etc to them for clarity.

And being on nextcloud, I can access those notes anywhere on any device, PC, Android, Raspberry Pi!! Joplin has an app for all of them
