There is nothing that comes to mind of not being available. Organizations worked and I have 2fa running with the 2FASAuth app. I only use it for my passwords so it doesn’t need to do much for me. Was there a feature you had in mind that might not work?

I use a vaultwarden hosted on a mini pc running fedora. It works with the apple bitwarden app and the bitwarden extension. I think any are good choices but it depends on your use case.
