Currently, the only items that are listed on the $1 $2 $3 Dollar Menu at the national level are $1 any size soft drinks, and $2 small specialty McCafe beverages. Back when it was first introduced at the tail end of 2017, the menu had about 11 options.
Thanks to the mobile app, you can conveniently take a look at the localized options for most McDonald's and get an idea of how different they can be.
Here's a sampling of the local value menu items and prices for a single restaurant in several markets (the menu and prices at some restaurants in the same market can vary a good deal as well):
