The only dlcs that are free are Curse of Osiris and Warmind. Amanda Holliday has Legacy missions available which will take you through those campaigns. Also you have access to The Tangled Shore, and The Dreaming City from Forsaken and also The Moon from Shadowkeep but you need to purchase both of those dlcs for access to the campaigns and other various quests and such. Here is a quote from an article: "Naturally, New Light doesn't come with everything. For example, while players will be able to explore The Dreaming City and participate in publicly available activities, New Light players will need to purchase Forsaken to play its story missions, the Last Wish raid, the Shattered Throne Dungeon, and so on. This will also apply to annual pass content like Gambit Prime, the Black Armory Forges, and Penumbra's Menagerie. It sounds like a nice compromise, and New Light should give new players a lot to sample."
