Cat 5e will work great. Local electrical code will say nothing about enet cable because it is by definition low-voltage Class 2 wiring -- no special protection needed. Be sure to get the cable you use with black jacketing. That's really about all you need to worry about given that you're probably not expecting this set-up to last for 50 years without maintenance. Natch, be sure that the building entry points have rain loops and the holes are sealed with caulk. Then you're good to go.
