The full-day plan includes stops at the Epcot Character Spot and Agent P's World Showcase Adventure, plus Soarin', Test Track, Mission: Space and Sum of All Thrills. Those can be deleted if the kids aren't quite tall enough or don't have an interest. The best Fastpass+ choices seem to be Mission: Space, Soarin', and Maelstrom. The plan ends shortly after dinner, so there's plenty of time to add in other activities like the Kidcot Fun Stops.
The afternoon plan includes Spaceship Earth, all of the attractions in The Seas, and the west part of World Showcase. Fastpass+ is used at Spaceship Earth, The Seas and for IllumiNations. The plan begins at 1 pm and has a bunch of free time before IllumiNations, so lots of time to revisit favorites.
