Don't you think the Coulomb is a rather arbitrary value with no physical meaning? The number of electrons flowing through a conductor is as arbitrary as saying 1 mile is 5,280 feetAmperes are defined as one coulomb of charge per second. A coulomb is about 6.24e+18 electron charges. So the coulombs cancel out and you end up with watts.

You should also check the old definition of the Ampere:
The old definition of the ampere (used from 1948 until 2019) was the constant current that, if maintained in two straight parallel conductors of infinite length, placed one meter apart in a vacuum, would produce a force equal to 2 × 10⁻⁷ newtons per meter of length between them.
Why 2 × 10⁻⁷ N not any other value?
As I said, the definition of Volt is the electromotive force that generates 1 Watt of heat at 1 Ampere (so the resistor is 1 Ohm). Volt is defined by Watt, not otherwise.
