We don't talk about Pun-Pun
Well, there is the Unarmed Fighting fighting style and they tried to give us the Brawler in UA. I don't think it's a stretch to let the Fighter be good at fighting without weapons in the same way they're good at fighting with all weapons.Can you give some examples of this? Because the class descriptions I'm familiar with all stress the Fighter as an armed combatant.
And really, the cestus needs to be a thing in 5e.
(As an aside, for the people who think this has never been a niche for the Fighter as the Monk exists, let me point you at 2e, where the Complete Fighter's Handbook gives the ability to continue specialization in Punching, Wrestling, and Martial Arts to the Fighter class. The Fighting Monk Kit would also gain this ability, but the Fighter had it first, and it applied to all Fighters, not just specialized Priests).
