Oh for sure reach out to your local USDA and FSA (Farm Services) branch. LOTS of programs and cost share to help with conservation practices.
If you are planting Forbes, make sure you're putting enough warm season grasses in there with it. The one thing with Forbes, such as wildflowers and different legumes, is they need fire every few years to help them out and keep thatch down and keep cool season grasses from taking over again. The woody stalks that are left behind in the winter do not burn well without grasses to carry the fire. The practice of prescribed fire goes back thousands of years to help with Forbes and wildflowers. I wouldn't get set on a particular wildflower or forb as diversity is King in nature.
Diversity also makes for a long season of availability. Some flowers are early, some are mid season, some are late season bloomers. In MO we have a diversity so that blooms start in March and the fields always have something into October. That holds insects and lots of seeds for turkeys and quail and browse for deer. But again, the deer on my place use it for night bedding and browse, only does use it in daylight for cover against younger bucks.
All that said, I can give you a list of flowers that I have definitely never seen browse on. But I would definitely make sure to have these in any mix you plant for the other animals that eat the seeds or insect that they bring
Those would be Rattlesnake Master, Purple Coneflower, prairie blazing star, wild bergamot (bee balm).
I have seen a lot of browse on all the milkweeds except for common milkweed. All versions of coreopsis and Black eyed susans and false sunflowers before bloom.
