At any point along the wire, and at any particular instant, whether as a

a phase. It has a direction.

In what direction is the RMS value of standing wave current flowing?

Those wave currents could not travel at nearly the speed of light
without the displacement currents.

You and I are talking about different displacement currents.
I'm talking about displacement current between a transmission
line and the ground. We had previously been talking about
displacement current between a loading coil and ground.

Then you are silly. You cannot describe the reason for wave velocity of
a conductor, transmission line or EM wave without displacement current.

How does the displacement current get to ground when it's
inside a shielded piece of coax with no common mode current
on the outside braid?

Displacement current into the space around the node.

How does the displacement current get past the coax shield
to the outside world?

So please stop saying that displacement current is negligible in some
cases of traveling or standing waves.

I'll even say it again. Inside a piece of shielded coax, the
displacement current to ground is negligible yet the standing
wave still exists.
