I appreciate the encryption key is almost impossible to break.
But if server 1 is connecting to server 2. Presumably once the connection is initiated from server 1 to server 2 - a public key must be passed between the two servers thus if one were to intercept the key (is this possible - I don't know) - then the SFTP connection is not secure.

Intercepting a public key doesn't break security -- that's why it's called a "public" key. Intercepting the corresponding private key would break security, but that's never sent (even in encrypted form). – Gordon Davisson – 2019-05-15T15:39:03.373
