The current does flow from positive to negative. Electricity is not the flow of electrons - they just generate the field that the electric wave flows through. The electrons don't actually move very far. The wave flows outside of the wire, not in it.

flows outside the wire, not in it

Yet it propagates at the speed of light in the material the wire is made of

It's not meaningfully outside until its outside an antenna

No, it propagates at the speed of light in space.
