Your question is difficult to answer so I’m going to answer it as best as I can. There are many options Rootstocks for Cherry | WSU Tree Fruit | Washington State University. I’m using Prunus cerasifera aka Myrobalan under sour cherry and there is a reason I chose it and that is versatility. I’m suspecting you or whoever your getting it from thought this out very well. By the way I grafted sweet cherry to the same tree without an interstem. Yes you can graft apricot and peach among other things to it as well but I’m going to use the documentation others have done as my experience ends with grafting cherries to it. Plums are a given but some work better than others. Before you ask yes people graft almonds , nectarines etc. to it as well but you need an interstem called Adara Adara (Puente) Plum - Fruit tree, rootstock & interstem. This is a great article Goodbye plum, hello cherry | Good Fruit Grower .

The documentation and articles will help more! Typically Asian persimmons use lotus rootstock but I can’t say why as I have seen hybrid kaki/American scion used with American persimmin rootstock many times. In my area true kaki will not survive the winter let alone years of producing so I will let someone in a warmer climate discuss kaki persimmon rootstocks further. They know over time how they do on american persimmon much better than I would. Since your zone is similar to mine I suspect your looking for cold hardy hybrid kaki/ American persimmons and as mentioned American rootstock works fine. @39thparallel has many of these hybrids on his farm on american that have been there for years.
