I said the closest we could get. A spark emits EM in almost a solid 360
degrees. But it emits particles called photons which are individual
entities at that stage of their lives.

You're talking about circular polarization. Haven't you heard of linear
polarization? That is transverse and determined by an alignment of the
electric field of all the photons in the beam.
Of course BaTh says that photon merge into a kind of medium that they
carry along with them and form into broader wavefronts in that
medium...but it can still be transversely polarized...not sure about
circularly though.

No you are very confused about this.
