>Elven swordsman seems like an interesting archetype
Not going to pretend to be some ancient grognard, only know this from the video games. But in AD&D like Baldurs Gate 1/2, or Icewind Dale 1, elves would get a bonus of + 1 for using swords and bows. Not that "automatically proficient with swords and bows" that does nothing if you actually want to play an elfen fighter specializing in this weapon.
At least there are bladedancers and bladesingers for 5e.
