>just want something open source like Joplin where I can put tags on my notes, but Joplin takes way too long to startup or switch profiles

Guess it depends on what you want exactly, but I use Memos (self-hosted) https://www.usememos.com/

I use it for dumping stupid ideas so they stop distracting me and for notes that may or may not become relevant later.
Memos is more centered around a calendar and tags, which makes it ideal for that. Fits your requirement.
