A second for some of those Debussy - the Fetes Galantes and Bilitis are definitely up there.
For Faure you’ve already heard some of the most famous via one of my favourite albums of all time. Clair de lune, Apres un reve, Le Secret.
Op.61 is also famous but also acknowledged as complex and difficult. It’s harder to get into than most.
If in doubt, for both composers I’m regularly fond of Verlaine settings!
