I don't believe I've ever heard anyone refer to Nyssa sylvatica as a fruit and nut tree, though I think I have read at least once that the fruit are edible. They are quite small, though, and I imagine any self-respecting bird would beat you to them as they ripen. The seeds will be even smaller.
Nyssa sylvatica is very well known to have the capacity for fine fall color - often brilliant red, and can have orange and burgundy tones thrown in for good measure.
You have a great tree there. Take good care of it, and prune it carefully so that your electrical/phone wiring isn't damaged nor requires a utility company arborist (aka butcher) to whack at it.
