I recommend Cat6, it is cheaper and definitely enough for your bandwidth requirement now. Also, you can run conduit, so that you can replace the cable easily.
I find a 2 fibers single-mode LSZH outdoor cable, which is $0.37 for 3 foot (2000ft is around $230. The cable is completed with the LSZH material jacket, which has good flame retardant performance. Besides, you can also custom the length of the cables for your needs. It may be suitable choice...
As many people have said above, you need to set multiple APs, at least one story one AP. Also, I recommend PoE, one Ethernet cable for both power and data transmission, that will simply your cabling.
