Trezor at home. The whole purpose of a hardware wallet is to sign transactions (send coins) so if you aren’t going to use it, better off wiping it if you have the seed.
Definitely use a passphrase if you’re going to use a bank vault. One copy of your seed in the vault and one at home (in the event the bank misplaces it).
If your seed is fully offline, a passphrase with a good passphrase manager isn’t a terrible idea since yes you need both the seed and passphrase to access funds.
