There are no furniture exclusive to Bastion. (Thankfully they stopped doing that after the Dunmer houses).
The furnished version of Bastion does include some Crown-exclusive furnishings such as 2 'Parcels, Wrapped', '1 Sack of Beans' and 4 'Vampiric Column, Ancient' for example. But all of those can be purchased from the Housing Editor for Crowns any time, so they're not exclusive to the house. And while the furnished version does include a lot of grand vampiric tables, chandeliers, and the new Greymoor paintings, those can be crafted or drop from Treasure Chests respectively, and can be bought for gold at traders.
