>convenience of cloud-based password management AND high security.

One attack vector I see with Bitwarden is that if the server hosting the web client or the Firefox/Google account that owns the browser extension gets compromised, they could easily be modified to exfiltrate all your data. So unless you always package the browser extension yourself and check the web client's code before using it, your passwords are essentially only as secure as the developer's security measures are strong.
