It’s mainly a difference in threat model. 2FA within a password manager is still 2FA for concerns of a website login being hacked by remote adversaries, which is the most important problem to solve.
If you use 2FA within your password manager, you should still lock that outer-most password vault with 2FA from a separate device (like you said), which solves your password vault being hacked by remote adversaries. Optionally, you can then use aggressive idle-locking of your vault on your personal devices, in case they’re stolen physically.
