There may be others on here who can help you. If not, I would post this question on the road trips forum. They are good at sorting out these long drives.
I do not know about scenery but certainly interesting places to stop and explore along the way if you have not before, such as KC and St Joseph, MO, home of the Pony Express and some Jesse James history. I would do whatever route also brings you in via the Badlands to see that as well although some enjoy Scotts Bluff Natl Monument in Nebraska.
