What would be a good self-hosted solution for a centralized file cloud?

Think of a Google Drive, but a centralized one; each user will be able to log to the central folder but depending on perms, will be able to perform different actions.

I tried ownCloud and Nextcloud, but it looks like they're more oriented to replace the "traditional" (for lack of a better word) cloud providers.

I'm looking to install it on an Unraid server, I've been looking for a solution like that for weeks, but my Google powers are no good for things I'm not able to describe in a few words lol.
