Porch Roofing

We have vacant 500 sqft area in front of the house, which we would like to use as a car shed and a sit-out. There is a wall to the right of this area. So we are basically looking at just putting a roof over the entire space.

We've been presented with asbestos, metal roofing, polycarbonate as various options.

We'd like a place that is well-lit (do not want sunlight out) & cool (keep the heat out).

The wall on the right is about 7 ft. tall and the roof is to be at 10 ft. Please suggest which would be a good roofing material to use.
