And even if these particles are virtually massless, wouldn’t that still be a tremendous amount of mass/energy pushing outward in all directions at light speed?

I have the same wondering as you. If there is an edge, what happens to all these lights and particles arriving at the edge? I can imagine three possible scenarios. They get accumulated. They pass through the edge into another space. They continue travelling along the edge of the universe. What do you think is happening?
