Here's an example why cultivars are not always as good as natives. The right most hydrangea has sterile show floresences, but not actual nectar for the bees. Brings them in, but then doesn't give them any food. The other one's shown have the infloresences that contain the actual food.

Deer resistant plants is a whole other topic. Those guys are voracious and they could avoid something one year and demolish it the next. I do love the showy hydrangea cultivars, especially when you can play with the pH of the soil for different colors. Just want to suggest having natives around to feed the buzzy bees also, which you noted you have and that makes me 💕💕💕
7' sounds awesome.
