I am well on record as making it very clear that whomever wrote the racial entries for Voldo's did a really, really
job and yet... in this particular case?...
I don't think the difference here is as great as you are making it out to be. Not unless your GM houseruled that if your race has a higher unarmed attack damage naturally, the monk bonus pushes it up a die size instead of nullifies it. But it is supposed to nullify the racial bonus giving you the same damage output as if you were a race that didn't have natural increased base damage bonus.
A lot of races have that, by the way, abilities that get nullified if you pick a class they would already be proficient in. While their burst of speed makes them effectively faster, the elf has resistance to sleep and charms and doesn't have to ever sleep at all. The elf also gets proficiency in swords and bows and that shouldn't be overlooked.
Now, a race shouldn't have been given two natural bonus skills, especially two so universally useful like Perception and Stealth. That's the part that jumps out as "this was designed by someone who didn't know what the F they were doing." However, if you get the stealth skill as an Elf then you can actually use it more often as you only need to be in light cover instead of heavy to hide.
Look, putting the Voldo's book and the smeghead who designed the PC racial stats in it aside, this edition has done a pretty good job, a FAR better job than any previous edition, of making just about any race/class combination functional. The only major slip-up in the PHB was designing the Half-Orc in such a way that you absolutely could not be anything but a Barbarian, Fighter, Paladin or maybe Cleric without basically losing access to all of your abilities. But half the issue there is the fact that they went out of their way to make Dexterity a god stat and did nothing to make Strength viable outside of those three classes... but the fact that the Half-Orcs other abilities require being in melee combat or getting hit often enough to lose all your HP before anyone else in the party. But, you know what? Being able to be 4 classes is way better than 3rd edition where as a Half-Orc you basically sucked at being anything but a Barbarian and even then you were sub-par.
Even the Aarakocra, as insanely broken as being able to fly and still having two arms free to do all your normal PC abilities, is-- its a stupidly broken ability with any class that doesn't have to wear heavier than leather (and in this edition, that means EVERY class since even the best fighter don't use heavier than leather!!)
So really, perfectly matching class and race is just not nearly the concern it was in the previous editions. So long as you don't include Aaracokra and you don't use the Voldol's book (particularly measuring the stupidly, insanely, wtf broken races in it to the 'my god, you were intentionally trying to make this so-called race absolute garbage, weren't you?') then the amount of extra mileage you will get out of measuring any race against any other is minimal.
But if you are looking for the race to absolutely destroy any other and your DM is dumb enough to use Voldo's Guide? Be a Bugbear. It is kind of hard to beat 5' reach and free 2d6 damage on the first combat turn.
