I don't think anyone knows enough about the universe to say whether or not there is infinite variety in macroscopic stuff
There are finitely many particles in the observable universe (that is to say, an infinite number will not fit), and a finite granularity to discern the position of those particles. That means there are finitely many configurations of particles within the volume of the observable universe.
Therefore, there are finitely many discernable things, so in a meaningful sense we can say with confidence that there's a finite variety of macroscopic things.
