Planning a road trip (move) from St Petersburg, FL to Portland, OR

Marti and I have been wanting to move to Portland for many years now and in the recent past, all of the stars aligned and we’ll be picking up and leaving FL early next year. I’ll be moving our belongings and vehicles across the country, so with many months to plan, I want to make sure that if I’m going to travel 3,500 miles, I’m going to make it the most enjoyable and beautiful road trip that I possibly can.
