In articles for the general population, you're right in both cases. For stars, you are also right in general. Well, we'd both be right, because for pretty much all observable stars light travel distance and comoving distance are equal (doesn't really make sense to talk about comoving distances or cosmological redshifts within a galaxy). In scientific populations, distances to galaxies are always given either directly in redshifts or perhaps in special cases in comoving distances.
