The password managers are: KeepassDX (Far Left), KeepassXC (PC version of local), Proton Pass (Better privacy) and Bitwarden (Far Right). Please note that bitwarden does some data collection. See their privacy policy here and their privacy spy rating here.
I wouldn’t trust proton. Data this sensitive has to be stored offline (unless you sent it encrypted) and only accessed with 100% open source software (no proprietary blobs). If you want to go extra tinfoil hat compile it yourself.
Edit: Left side recommendations are good, though.
