I have not heard of anyone using Yoshino cherry as a rootstock. Isn’t Yoshino cherry usually a big tree similar to mazzard in size?
You probably want to look at the Eastern sweet cherry thread. It deals with growing sweet cherries in humid regions with Summer rainfall. There are also recommendations as well for cultivars.
Basically you want to plant cultivars that are adapted to the East, spray for brown rot and net or place bird scare tape on the tree. Dwarf and semi-dwarf rootstocks help too such the Krymsk and Gisela series. WhiteGold and BlackGold are usually recommended for the East as are a few others. Bing isn’t recommended in the East due to fruit cracking problems. I suspect Utah Giant would also have cracking problems. Sweet cherries are harder to grow in the East than tart cherries due to brown rot and fruit cracking.
