But the mechanical incentives are considered strong by many players. My sister for example always plays a elf fighter/magic-user, and no other race can do this better than elves (also taking into account the elves' other specialties.)As long as players aren't strongly mechanically incentivized to play nonhuman over human, and your campaign setting provides some interesting human cultures and history to provide character hooks for them, I don't think it's necessary to give nonhuman characters the hose to accomplish this.
In 2e the option was given to raise the maximum levels based on ability scores, and of requiring 2x and 3x XP to unlimited advancement; this works well in my experience. In particular 2x XP from level 1, and 3x XP from maximum level, makes level limits relevant at all levels of play.
