We know there must be a limit to star size because physics decrees there is a segregation rule pertaining to star formation that limits their volume to be somewhat less than galaxy sized. You could have a condensed galactic core/centre where the largest stars might be found, however, that is also where SMBHs are going to be located. My guess is that at this stage of evolution of our universe, if black holes exist, they should have had the time to coalesce with baryonic matter and accumulate in size. So I think the heaviest objects by mass could very well be black holes unless dark matter and dark energy are clarified.
It is a very curious state of affairs. Stars shine and radiate via internal fusion, while their alter selves are dark and pull in anything within range. The only radiation they give out is externally, in the hot accretion disk, should there be one. Even if black holes do not consume everything, the universe will darken anyway with the coming heat death. I take it that virtual particles will still pop in and out of existence, so that Hawking radiation can occur. In this manner, way, way into the future, the black holes themselves will evaporate. An then, what are we left with?
Then again, if the collapsed matter has allegedly fallen out of our universe, why should there be any gravitational effect left behind at all?
That one hurts!  A residual property left there by virtue of the fact matter can neither be created nor destroyed? It is a form of information testifying that a star was once there on this side of existence. It is a curiosity that some of the light emanating from a star will disappear into the light cone of some other causally connected black hole. Your question really does cause creaking when you think what happens to the personal experience of a photon, unaware of time in or out of a black hole?
