I think that the additional weight on the water on the surface of the outer airplane body increases friction with the air, and also weight of the aircraft. But does the fuel consumption increase? And by how much?

We do account for barometric pressure, but it’s generally a few tens of feet. So yeah, a teeny tiny bit, though you can have low barometric pressure without rain.
