How about in the situation above a door way, for example, where an

You have the horizontal piece coming together with a vertical piece.

Would you do a "reverse" miter? Where the material on the edge sticks
our farther than the corner?

Nope. Those "wing" adds nothing. Use a piece of joint tape diagonally
across the corner of the two pieces. It'll prevent most cracking at
that point.

Thanks for quick and concise answers!
