Google ‘wall duct’ for a commercial raceway system that can be recessed into a wall and is suitable for both line and low voltage conductors, including both in the same raceway if you use a divider to separate the line and low voltage conductors. A less expensive option would be woodwork that covers a channel in the wall, romex and Cat6 cable don’t need a raceway so you could skip the wall duct. If you want to get fancy, add some hinges on the woodwork to allow for easy access :D
