When looking into KeePassXC, did you specifically look into the KeeShare[1] feature? As long as you have some common place to read/write a file, you can share a subset of your credentials. I agree this is not as easy as hosted solution like Bitwarden, but KeePass was always designed to be a non-hosted solution, so I think this is about as good as they can do.
GP here. Yes, I did look at the KeeShare feature, and that's what I had in mind when I said seemed not as easy to use. I'll have to read more and try it out practically.
