We can't design this for you.
What do you mean stray voltage? From where?
Follow the code.
Pole type is whatever you would like.
Luminare poles must be bonding to an effective ground fault path - size per 250.122
Isolation transformer won't solve an energized pole hazard.
Fuses are optional, recommended.
Code has no maximum voltage drop only a FPN.
Try googling for street light specs, look for some boilerplate.
Never belive that a ground rod will solve stray voltage or clear a fault.
