Door is going to be on the 10 foot wall of a 10x8 shed. Are there any
practical considerations as to whether it's in the center of the wall

cofiguration result in a better use of available space? Thanks...

Seems it would depend entirely on what you use the space for, what kind
of door and how it opens. If you use it as a shop, you don't want the
door to hit you if someone else enters. If you have a monster lawn
tractor to drive in, then perhaps the door should be at the end where
you park it. Hanging, sliding door might give you more useable space.
