For my more sensitive, shorter attention span younger boy (age 10), he’s enjoying Grandma’s Attic stories, a finely illustrated Wind in the Willows unabridged, Understood Betsy, Narnia (usually the audio drama, but he’s working on reading it too), Lamplighter audio dramas and books, Trumpet of the Swan, picture books with animals/illustrated chapter books, The Dangerous Journey, bug field guides.
Aloud together: in addition to also having read the above lists, some favorites also have been Little Lord Fauntleroy, Heidi, Swiss Family Robinson. Books by E. Nesbit (like The Railway Children) and George McDonald (Princess and the Goblin…). My oldest,12 yr old ds, has read these on his own also and enjoyed them.
