Recommend me some interior colors that are neutral and modern. Steering towards gray

Any input? Need a color that will look fresh, modern, and neutral so that if I decide to sell the house in a few years it will be acceptable to most buyers. Currently have a light beige color that the previous owner did and while beige is always a safe color, it reminds me of the 90's and early 2000's. Plus I'm getting tired of looking at it. That said I'm leaning towards white doors, trim, and ceilings while painting the walls a light gray.
