> I really liked Bitwarden but the incredibly delayed Passkey support that hasn't even reached mobile yet left me worried about the future development of core Bitwarden.

According to the developer of Bitwarden[0], part of the reason passkeys haven't been supported yet on mobile is due to the use of the Xamarin framework, which doesn't have cutting edge features. They're about to release new versions of the mobile apps, part of which is upgrading to the MAUI framework. This will provide a stopgap to allow passkeys until full native apps are available. They're developing the MAUI and native versions in parallel.
