While digital has a lot of advantages, the Switch is a portable, game-card-based physical system, with very limited internal memory. So one advantage of physical games (for the Switch) is to preserve the internal memory, as they run as fast from the game card.
Other consoles typically install games on an internal hard drive from an optical CD, which is similar to digital ditribution, minus the download, so they aren't much better. A much better physical medium would be cartridges, but there aren't many gimnicks that can be put in them that aren't already available in the consoles themselves (gyros, rumble...), except maybe going back to putting the data directly accessible as RAM-like extensions for instant loading times...
