As another example, a photon sent by a star when it was a million light years away might take 10 million light years to arrive simply because space/time expanded while it was en route.
***So if that photon were travelling at 20X the current speed of light, then it would have gotten there before the mass of space/time.

Did the Big Bang/ Ultra Inflationary early period of the universe last that long? My impression is that it was perhaps the first few seconds of our universe, not nearly long enough to form a star.

The inflationary epoch was a mere 10-32 seconds - hardly even measurable.
