That is the answer. SSO, then password manager. I'd strongly recommend bitwarden, having deployed and managed it. I would warn against lastpass, strongly, due to papercut level issues everywhere. I haven't used 1password in an appropriate scenario to comment on it.
We have SSO + 2FA in place, and would like to use Bitwarden for the rest of the password management. But for a company around ~50 people, the pricing feels too expensive, considering the only purpose is to manage a few passwords. So for now we are using Keepass which is kind of painful, but free. We would probably be willing to pay ~2$ per user per month, but instead it is 6$ if you want Bitwarden to work integrated…
We ended up using Dashlane because its free tier allows sharing between users but the administration is so much more work than it needs to be.
