Also the standard Shahed-136 style drones carry less than 200 pounds of explosives, and deliver that to the surface of a target.

Antiship missiles carry larger warheads, often double the size, and deliver that warhead deep inside a warship where it is much more vulnerable. A shahed blowing up on a carrier deck will be upsetting but won't do much. With particularly egregious negligence of standard US Navy damage control methodology, you might cause a lot of damage by fire, like what happened to the Ford. Not that I'm suggesting it was hit by a Shahed.
