You are incorrect. The Magisterium does refer to things not taught as “infallible” in that they are definitively dogmatic teachings, teachings that are taught to clear up a disagreement say through the ordinary magisterium to prevent tension in the Church, but at the same time, can be brought up again for further theological discussion in the future. So strictly speaking, when the Pope invokes uses infallibility to define definitively a dogma, that is the most “forceful” use of infallibility. The last such case was the Dogmatic Apostolic Constitution [which was issued in the form of a Papal Bull {which in and of it self is not infallible, since a Bull is just a form of a Pope’s Letter in that it has the Pope’s seal on one side, and icons and seals of SS Peter and Paul on the other] on the Assumption of Mary.
My point is that ex cathedra is not the only way the Church and pope teach infallibly.
I am not incorrect. You are either incorrect or have misunderstood me .....again.
