2700 users? I'd classify that as more than a "small" or a "medium" server myself. That's definitely in the range where setting it as a "Community Server" could be beneficial for a lot of other reasons.
What are these reasons? It's a pretty niche server, focusing on a specific language family, and I doubt the admin or the other moderators would really want it to be super available. We also have probably active users, which is probably why I would consider it small.
To answer your question, though: Community Servers get a couple more security and safety features that help with moderation. They get a "Welcome Screen" for helping new users not feel quite so lost on first joining the server. Discord is generally better about notifying Community Servers of upcoming updates and slower about rolling out new features to them (such as Threads).
