How big is the site, what's the soil like and how much sun does it get?
There's a lot of plants there with differing needs.
I can't immediately see the wildlife connection though any single flower may well provide for insects.
I'd spend the winter doing some research, see what will grow on your soil and aspect, pick out those that are good for wildlife if that's what you want, some will be, and plant in spring
