A Fey Wanderer optimized for Control is amazing at control from level 7-16, amazing as a face from level 3+ and it is ok at damage and exploration at all levels, but you need to go all in with Wisdom and feats to do it. The best feats for this are things that cause charmed and frightened, specifically Magic Initiate as your Origin for Cause Fear and Friends and Shadow
Touched at level 4 for Wrathful Smite. Fey Touched for Dissonant Whispers is also a good add but probably not worth delaying Wisdom 20.
For race if you have 2014 species you want an Eladarin or Leonin or if you have both 2014 feats and species a Dragonborn (Dragonfear Feat). If you are stuck with 2024 species I think you want a celestial.
IMO if done this way it can be one of the strongest "Martial Classes" and probably the strongest martial class if you are looking across all 3 pillars, but it is not one of the strongest characters when it comes to martial combat.
