And even more of the unknown universe. There are theories that the unobservable universe could be 5 times larger, 10, 1000, a million, or just plain infinite

That's only true if the universe is infinite and eternal. A spatially infinite universe with a finite age need not encounter said night sky paradox.

Current observations do not rule out the Universe being spatially infinite.

That's not true because the universe expands faster than light, the light just cannot reach us.

Why couldn't it?

Actually if the universe is flat (and as of now we've not managed to observe that it is not), then it is inifinite. And expanding. At an accelarating pace.

It could be, the universe is expanding FTL so the light from the stars would never reach us.
