Having 300 tags doesn't mean they have to be disconnected. For instance, you can have around 50 tags related to nature, like #nature, #nature: animals, #nature: plants, #nature: landscapes, and so on. The important thing is not the number but how you organize them.

Unfortunately, the plugins currently support only the PC version. If you want, you can open a feature request for this. But currently, the mobile version is a bit more limited compared to the PC version. For example, you can't edit tag names on mobile.

In my opinion, Joplin is the best note-taking application. Once you get used to it, I don't think you'll look for other apps. However, you should give yourself some time to learn it and use the forum when needed.
