The paper derived results for stellar mass black holes, but why not do the same for super massive black holes at the center of galaxies?

Yes, this would be constrained to ultra-advanced type III civilizations. But it would let us search for ET civilizations across the entire universe, not just our own galaxy.

Don't aim too high. Not because I don't think we would find anyone, but because if we did, who cares? Information reaching our galaxy would be too low resolution to learn much of anything, so the whole thing might end up being a distraction from searching for someone closer to home.
