I still use Tomboy Notes synced with Nextcloud & Dropbox. It's ancient, but I've never come across anything else that does these things:
- temporary sticky notes.
- permanent sticky notes.
- glorified clipboard buffer.
- personal wiki.
- light weight (no browser, database, or network required).
- one small window per note.
- optional categorization into notebooks.
- desktop pkeyboard shortcut for searching notes or opening new ones.
I really hate web based notes. I want small quick responsive windows beside my browser.
