So if you were going to web some seats, what size and type of webbing would you use? Standard 1"? Polypropylene, nylon, polyester?

Definitely polyester webbing for seats and cartop straps because it is equal or superior to both nylon and polypropylene in every category. See this Straworks chart. Strapworks sells polyester webbing in both regular and seatbelt weave, the latter being lighter in weight. I'd use 1.5" for seat webbing.
