A faraday cage distributes the charge on the outside of the container, whether it is grounded or not.
Anything inside is protected
But grounding is not a bad idea too.
So, here’s the scientific question:
Does the faraday cage shunt an electrical charge via the “skin” of the metal or does it involve the entire molecular structure?
As a chemist (who once worked in a metallurgy lab) I would think the entire molecular structure would be involved as the electrons would jump from molecule to molecule.
I’m willing to be dissuaded.
It would prove helpful if you would read the previous, including...

A Faraday cage only works on static electric fields. An EMP would not be static. It’s a pulse, an impulse function...
