Space still expands lower than light speed, the moment expansions goes faster night skies will be completely dark because other objects' light won't be able to reach our field of vision. I do not remember how that phenomenon is called.

Not really. The far edge of our perception can be at lightspeed, but then everything closer would remain slower. So night wont suddenly become dark. We will first loose distant galaxies, but 99.9999 of starlight comes from our own galaxy. By the time that is moving away at lightspeed, the view will be the least of our concerns.
Or the night skies light up completely because there was another big bang somewhere else and the light from that universe cluster just reached us
our observable universe may be around an unobservable area whose light hasn't reached us yet

so a parallel universe somehow interferes with ours? I don't think even most enthusiastic multiverse theorists will be able to grasp that.
not really parallel like alternate dimensions, maybe adjacent to not get distracted by colliqualisms and scifi tropes?
just another area in the vast void that also had a big bang which is outside of our observable area right now, but whose light may reach us one day.
