How do home ovens have hotter or colder zones inside, requiring you to rotate the pan or whatever is cooking. Wouldn’t a small enclosed space have a consistent temperature throughout? And bonus follow up, what sort of degree variation can there be?

A small enclosed space with a single source of heat won’t have a uniform temperature distribution; the temperature is hotter near to the active heat source. If you let the oven warm up and condition itself so that the metal walls are hot, the metal walls re-radiate heat passively into the space, creating a more even distribution. If you have a convection fan in your oven to move the air around, the temperature distribution is much more uniform.
