Ignoring the incredible plethora of preexisting COmics and only going by the MCU (which includes only considering beings IN the MCU) I`d say that Captain marvel has the highest Powerlevel of the "can easily and without much effort/Specific Circumstances apply her powers all the time" Characters.

A superduperenraged Hulk can beat her.
A Scarlet Witch risking killing herself via nosebleed or distraction or as sideeffect of killing her could beat her straight up easily enough....but carol is fast enough that would not happen.

Thor....with all recent Pwoerups still is weaker, but not by much.

Stranges only chances would be to flee, and rewind until he gets it right.
