Bitwarden is fine. Being in the cloud means I can use Bitwarden on my laptop, PC, and phone and share account logins with my spouse. I host lots of things myself but a password manager is not one of them. I don't want to be so secure that I end up locking myself out of my accounts.
There is a non-zero risk with using a cloud-service of course, but I think it's pretty minimal and you need to balance that with the realization that non-cloud/self-hosting is not risk-free either, and may pose a higher risk.
Being in the cloud does not equate to being insecure. The local vault (from the last time you accessed it) is also accessible via your master password if cloud access happens to be unavailable (e.g., your device is offline). And as a backup I export all my passwords as an encrypted vault every 6 months so just in case Bitwarden vanished, I'd still have almost everything.
