Solo
Shadow Priest
I personally like them, but there are stages with little interactables. Ranging from 2 to 4 things.
Batcave - Lab and Lagoon.
Themyscira - Temple
Fortress of Solitude - Lab and Menagerie
Wayne Manor - Entrance
*Note - If you're in the Great Room, and you have a power character you can destroy the interactables.
Gotham City - Rooftop.
*Note - If you're in the Alley, and you have a power character you can destroy the interactables.
Stryker's Island - Cell Block
Those are stages I believe have the less interactable stuff.
