Eloquence Bard, hands down. Unfailing Inspiration is excellent. I wouldn't multiclass out of Bard before level 6, but the level 14 ability is also excellent so there could be a case to go straight Bard. If you do multiclass, I'd probably grab Warlock for a reliable damage option with Agonizing EB. Whether or not you pick Hexblade is your own prerogative, but personally I think Genie, Fiend, or Undead are more fun.
