I like to know the details of how capacitors work?
Since I certainly read volts, it must imply that energy ( I had to
throw in that word) moves without any charge movement, unless charges
actually do move in an open circuit.

I don't see how the reading of volts implies that energy has moved. (Unless you take the non-finite impedance of the voltmeter into account, but then you must acknowledge that charge has moved)

Capacitors by actual design is an open circuit no matter how close are
the plates. To my understanding, that is the whole idea, not to allow
charges to move through.

In a static situation, capacitors are indeed an open circuit. No doubt about that.

( I realize also that Antennas are basically open circuits....)

Like capacitors, they are open circuits in a static situation. Antennas do not transmit DC.
I think you are confusing static and dynamic behaviour. Consider a capacitor as a reservoir of charge. Each conductor has this property, but capacitors are designed to have more of this property. Likewise, inductors are a reservoir of current (much like a moving object has momentum), but in a static situation an inductor behaves just as a wire.
To put it into different words: a capacitor is something that hinders change of voltage (over the capacitor), and an inductor is something that hinders change of current (through the conductor).
