For tart cherries I would also consider Montmorency. I have a Montmorency on Gisela 5. It’s very productive and produces well even in difficult years. The Balaton I have on mazzard is very unproductive and other people have also had low crop yields with Balaton.
Sweet cherries are much more difficult to grow. If you do want to try them Black Gold and White Gold are both good choices. Both of them bloom late (Black Gold is really late).
For sweet cherries I would look at this chart that details bloom times (and overlap between cultivars) as well as pollen compatibility.
For good discussion about growing sweet cherries east of the Rockies see this thread.
