I agree with this sentiment, but I’ve always wondered about a person’s face or appearance and how that might correlate to other traits.

I think we could all agree that a person’s face might indicate ‘shiftiness’ or ‘meanness’ and that there is a decent probability that you’d be right in your assessment.

Has there ever been studies that correlate face types with personality traits?

It's an attractive idea that the surface of one's body can tell you something about its inner truth, but it's incorrect. The field is called physiognomy, which is a pseudoscience that's been the basis of scientific racism and eugenic programs.

Some names you can look up are Johann Lavater, as well as Alphonse Bertillon, inventor of the mugshot, and Francis Galton, inventor of composite portraiture.

I've heard of various bits of pseudoscience around that, including in eugenics and criminology.

One of the times, it escalated to genocide, and the people who committed that are widely known to history as the epitome of evil. They were trying to characterize and identify "lesser" people, and it turned out they themselves will be known forever as the worst of humanity.

There's some curious questions (e.g., why do so many overtly mean people we've seen look mean). But I suggest being careful with this space, and skeptical of people who are motivated to pursue it and those they attract.
