Former film student here, this is all correct but I wanted to rephrase part of it- Most of the time, you don't need to worry about focal length ( especially because it's so complicated when you're trying to talk about different sensor sizes) The real measurement here is distance from the camera. The further you are physically from the camera, the flatter things look. Now, when you're further away, you obviously need to zoom in to make your head fill the frame, but it's way easier to think about it in terms of distance first, and then find a webcam/lens/crop that works. I use a pro camera as a webcam (with a cheap HDMI/USB stick), and I have it mounted on my desk around 3/4 feet from my face. That seems to work well for my face shape. |

So, to underline the "position yourself farther from it" part of my post where to go from a wide 4K to a cropped 4K the important part was moving back, and underline the distance from the camera part of your post, readers may enjoy this movie on the "dolly zoom":

The face distortion bit starts about 1m15s in.
TL;DR: To fix your face, zoom out with your feet! Then zoom in with your lens, or crop back in, to frame.
(All that said, if you're shooting faces, aka a portrait, consider a "portrait lens", and for this you're back in focal length talk. Pick 85mm focal length or longer, though I'm partial to 105mm up to 135mm myself.)
