Joplin is reasonably good as long as you don't use so much metadata to keep things organised. It's also pretty rigid, and hence limiting. If you want something with the superficial simplicity of joplin, but that would scale up to your needs, I recommend giving https://triliumnotes.org/ a good look.

Vscodium for notes, interesting.

I looked into joplin before obsidian actually, but it is much more of a standard note taker, not good for zettelkasten sort of notes (link and tag focused)
