For a given GPM, choosing a larger-diameter hose will have what effect on friction loss per 100 ft?

For a given flow rate, increasing the hose diameter reduces friction loss per 100 ft. This happens because larger diameter lowers the flow velocity and wall shear, so the resistance the water encounters along the hose wall drops. The practical rule is that friction loss scales roughly with Q^2 and inversely with D^5, so doubling the diameter dramatically reduces loss (about 32 times less for the same flow). The nozzle type doesn’t change the hose’s internal friction loss for a fixed GPM; it mainly affects the discharge characteristics and overall system head. So, larger-diameter hose decreases friction loss per 100 ft at the same GPM.
