> - Easy password sharing with my wife. We have separate private vaults and a shared vault, and moving a passwords between these vaults is seamless.

Not sure about this one. I don't even collaborate passwords in Apple keychain with my own family.

> - Sync has been seamless for years. I don’t have to worry about e.g. iCloud corrupting my password database and having to restore from off-site backups.

Sync with iCloud Drive, Dropbox, Google Drive have been fine for a long time. Plus theres also the option to just keep a password database copy handy.

> - Integration with many platforms. Currently, that means autofilling/autosaving/generating passwords in common browsers, on MacOS, and on iOS.

KeePass is usable on more platforms than 1Password sorry. You could probably get one keepass app or another running on some ancient power PC box running netbsd..

> - Generating and filling TOTP tokens (no need for Google Authenticator or similar apps).

KeePassXC does this

> - Storing and syncing SSH certificates, including acting as an SSH agent (so I have to scan my fingerprint to allow a new SSH authentication).

I have not tried this one, but would be surprised if KeePassXC doesn't do this as well

> - Storing non-password items in the encrypted store, e.g. pictures of passports.

KeePassXC definitely does notes, not sure about photos etc. This is definitely the realm of an encrypted Apple Note for me though.

> - TouchID or FaceID for quick unlocking with everyday use.

KeePassXC has this on Mac, KeePassium does it on iOS really well...
