I'm not even close to an expert, but from what I have heard, matrix collects quite a bit of metadata depending on the server you are using/federating with.
Yes, it does not protect metadata great. It is visible that you and your interlocutor are talking together and when.
But noone figured out how to prevent that in federated systems. You rather have less metadata in centralized place for everyone or more metadata but only for small subset of people.

You've basically got a choice been a centralised service where metadata can be limited but E2EE is mostly pointless (you have to trust the service operators' E2EE deployment), or a decentralised network where E2EE is reliable, but it's harder to limit metadata.
Which one is best depends on the situation/ threat model.

Yeah, I have been concerned about that. Looking into self-hosting matrix.
