Well, for starters, you are admonishing human's very much. Even in 'FR,' there are humans who can more than match elves, strike to strike. Saying that an elf is just outright BETTER than a human is somewhat ignorant in and of itself. Beyond that, you might also be mistaken on your definition of 'peak human.'
The most common definition is 'the best a human can possibly be,' which makes sense, from the wording. However, Captain America is stronger than any human would ever be, he is faster than any human (and a lot of meta-humans) could hope to be, and he has survived the likes that few humans have ever witnessed.
Captain America is an AMAZING combatant, but not only hand to hand. He can adapt to nearly anything, and uses his shield with the utmost of efficiency.
True as it may be, that Drizzt has more abilities, and is more versatile, Captain America would still win in the head to head fight. Too much power behind his hands. What's more - Captain America doesn't even need to end Drizzt's life, a quick knock to the head with his shield would likely be capable of knocking him out, without ending his life.
There is so much Captain America underestimation on these boards (and, admittedly, a bit of overestimation in the canon comics), he is more than most people think of him.
