Playsets would include battle packs and regular minifig-scale vehicles or location sets.
Display sets are the dioramas with black bases and quotes, as well as buildable Droids/characters, and midi-scale/UCS ships.
So from 2023-24 the playsets would be:
All four Ahsoka series sets (Ghost, E-wing, T-6, Peridea Battle)
The Mandalorian sets (Spider Tank, Pirate Snub Fighter, Fang Fighter vs TIE Interceptor, BARC Speeder, Paz Viszla/Moff Gideon Battle, Ambush on Mandalore)
All three Rebuild the Galaxy sets (Dark Falcon, Bob's Starfighter, X-Wing/TIE Mash-up)
Battle Packs (Clones vs. Droids, 501st Specialists, 332nd)
Young Jedi Adventures sets (Tenoo Temple, Crimson Firehawk)
Yoda's Starfighter
TIE Bomber
Coruscant Guard Gunship
Yavin 4 Rebel Base
Boarding the Tantive IV
Darth Maul's Sith Infiltrator
The Onyx Cinder
Desert Skiff & Sarlacc Pit
Imperial Star Destroyer
Maybe the Holiday Diorama?
Not sure how to classify things like microfighters and mechs though
