It sounds like you have need of several shrubs, I'd get all different ones, offering different treats and cover for the wildlife, especially birds in your case.
Beautyberry (Callicarpa) is worth mentioning, I think. The purple berries are really cool, native, birds love to eat the berries, makes flowers although they aren't the wow-across-the-yard kind.
Osmanthus fragrans would fill your need for something wonderfully scented occasionally, more of a wafter than roses, IMHO/E. A well-placed moonvine is great for that also, where convenient for sniffing, early morning or late evening.
Confederate roses (Hibiscus mutabilis) are hardy in your zone I think, would fill your need for pruning (LOL!), though it's a one-time thing in the spring, just cut everything off and stand back quick, so the new growth doesn't whack you in the head. Please look at pics to remind you about its' girth/height before picking a spot.
Another vote for Gardenia!!
Edited because I forgot to say - the more varied your planting, the less likely any disease can wipe everything out, like the current monoculture/overculture of roses. This is also why I like to put veggie plants in various spots around the yard instead of all in one patch, when possible. Pests don't usually find all of any particular thing.
