Exactly. The reflected current has made s round trip of 180 degrees plus
the reflection has added another 180 degrees for a total of 360 degrees
or back in phase with the forward current at the feedpoint.

At the open circuited ends of a resonant antenna there is almost double
the forward voltage

Could you tell us if the "almost double voltage" is the measured of
theoretically predicted?

but zero total current due to cancellation of the
dorward and reflected currents at the open circuit. At the open circuit
in the wire, all the energy in the wave is transferred to the electric
field.

The relationship between the input power of a given antenna and the
strength of the far electromagnetic field which it will produce depends
among other factors the length and shape of the antenna.
