Galadriel and Cirdan were both wiser than Elrond.
Cirdan gave the ring to Gandalf, showing a. discretion (chosing him over Saruman, who was the eldest of the Order) and b. modesty (it was *his* ring, but he felt Gandalf could use it better.
Galadriel, through her Mirror, showed insight and wisdom. She backed Gandalf, too.
Elrond, meanwhile, didn't want Merry and Pippin to join the Fellowship.
Melian was extremely wise. Ingwe was circumspect - you can call that wise I suppose. Finrod, yes, definitely. Maedhros, yes, eventually. The Union was pretty wise.
Celeborn was wise in that he listened to Galadriel.
And Tom B and Goldberry should be there too I expect.
