What you refer to as a photon I refer to as a particle

So do I. "The photon is the gauge boson for electro-
magnetism." Particles are easier to understand than fields.
According to quantum (particle) physics, everything that
exists in reality is a particle, i.e. everything that exists
is quantized.

Would you have it that a capacitor retains
protons which is a particle?

A capacitor retains electrons which can be collected
on a capacitor plate. (Photons cannot stand still and,
by definition, always travel at the speed of light in
the particular medium. This includes photons in standing
waves.)

"In the Standard Model of particle physics, electrons belong
to the group of subatomic particles called leptons ..."

With my analysis it has a trail but yours seem to be just snippets.

My snippets are sections from the standard model about
which I will choose to stand on the shoulders of giants.
