@nteodosio pointed me in a side-channel at the "account settings"->"End to end encryption" options, where the key needs to be added for Thunderbird to actually consider encryption. With the wrapper, this is working as expected, and TB is correctly able to find that my host's GPG agent indeed has access to a private key on a smartcard, and is then successfully able to send out encrypted messages. The weird thing here, is that it has its own cache of keys, and no matter what, it won't be able to find other public keys listed in `gpg -k`: you'll need to import recipients public keys in TB manually. That seems to be how TB implements its key cache, and has probably nothing to do with the snap.
