Bitwarden is an incredible piece of software. I would recommend anyone looking at self-hosting an instance to look at VaultWarden. It's an alternative implementation to the official Bitwarden server that enables almost all premium functionality.

My only complaint with Bitwarden at all is around offline vault editing (which is such a niche use case). Right now, if you lose connection to the server (either your self hosted, or the official Bitwarden Hosted instance) you are only able to view your vault in read only mode. They have an item in the road map to allow offline editing, but it looks to be a long way out.
