My question is about the materials I plan to use. Instead of the flimsy angle iron most are constructed of, I am thinking of using medium gauge 1" square tube. (Or 3/4") Any ideas or suggestions.

I will be using a Miller 251 Wirefeed Welder
1x1 is waaaaaaaay too small for a trailer, don't even consider it. I've got a 3000# 5X10 trailer (Big Tex 29SA) that's all made of 2x3x3/16 angle, and it handled a 4500# cube of 8" blocks with NO flexing at all.

trailer mf'rs use angle because it's cheap and it works.

My 7000# 14' homesteader challenger (714CT) uses tube for the main frame rails, and angle for everything else. there's no discernable flex in that one either...
