Other fruit tree guilds

I am looking for better companion planting information for plants in specific fruit tree guilds. I would be very interested in plants that are not just the standard general to all fruit trees. Fruit guilds of interest:
Cherry
Persimmon
Pawpaw
Mayhaw
Plum
(These will be established as seedlings and young saplings, not as container trees or existing trees.)
Thank you for any insights!

I think that the more important idea, as some have said here, is to diversify in terms of plant families. For example, I have a lot of cherry trees, but there is only one sweet cherry. Next to the sweet cherry is a kiwi, grape, aronia, dandelion, Russian sage,palms, goumi, quince, autumn olive, forsythia, paw paw, persimmon, None closely related. Different flowers and green leafies are intermixed, for example, tulips, daffodils, grape hyacinth, comfrey, evening primrose, native honeysuckle, native spirea, linden tree, loquat, iris, dwarf walnut, flying dragon citrus, curly mallow, leeks, columbine, candytuft, etc. I'm also laying on wood chips to increase the fungal diversity and growing an intentional King Stropharia mushroom bed. Diversity of kingdoms! Mostly I've only got one of each variety and they are staggered. Works for me. Wikipedia shows the geneology of each plant so you can figure who is a pome fruit, stone fruit, rose family, etc.
