`pass` is a CLI application. It has tab-autocompletion and everything. It doesn't get more efficient than that (tip: use `pass find` to search for entries).
> different storage engines
It's just OpenPGP encrypted plain text on disk, not sure what more you could want, but there is support for Tomb (https://www.dyne.org/software/tomb/) as well. Anything you expose to the filesystem works of course, including services like SFTP.
> shared vaults
Syncthing or git, and the use of multiple OpenPGP recipients. (See `.gpg-id` in the `pass` man-file.)
> categories for secure non-password stuff like credit cards,
It's plain multi-line text. The only convention is that the first line is intended for the password or secret data that clients would copy to the clipboard. You can store whatever text you want.
