The current does not flow through a CMOS device in a conventional sense. Single nanoamperes, at most, but when you have billions of transistors that stacks up quickly.

In CMOS, only one device of a PMOS/NMOS pair is open at the time. In simplest terms: electric field gets through a CMOS device, but not so much of current.

And what happens during the switching transition then? Answer: both conduct for a very short period, hence the dependency of power consumption on frequency.

There are two factors to that. Cross conduction is one, the other is the current pulse needed to charge the capacitance of the switched signal (the trace capacitance but also the gate capacitance of the next stage(s); of course this simple model is only an idealized concept with current process nodes).

Yep, just enough to flip the device state.
