The siding itself isn't all that thick and easy to drill but if you hit the inside partition then they take time to drill as will the chair rail at the bottom of the wall.
With 2x2 you are looking at 3" screws. If your pilot hole is small enough, then drywall screws grab good but I don't know about longevity. Should be fine I think. Any screw make that is at least a #8 should hold well.
