C4 used to be the landmark constellation, because of the anemo shred, which was once virtually impossible to come by. However, C2 adds attack speed, which is not a super common stat, so in that sense it's valuable if you're pairing her with a normal attacker. There's no one team that specifically wants Jean, outside of Sunfire nonsense, but she's fine in basically any team that can flex their healer. I've seen C2 used, for example, with Eula on Broken Pines to get more attacks in before the burst pops.
