I see a lot of emphasis on movement speed, however given that you can cast longstrider as a ritual spell on your whole group and there are other ways to improve mobility with spells and class features, I really don't put a whole lot of stock in movement speed for wood/half wood elfs nor do I ding the smaller races much for having less.
Darkvision is another stat that has a lot of emphasis seemingly placed on it but I feel like it's necessity is over-stated, especially given that the majority of races and sub-races have access to it and there are also spells, class features, scrolls, and other methods of getting this ability, and even more ways to simply provide light. That being said, Superior Darkvision is pretty good for ranged characters and you might see more use from this if you're doing a stealth heavy group/strategy. I try to approach every combat and encounter in the game "naturally" without sneaking around the whole game however. Something about premeditating every combat, unless it's obviously going that direction, just feels cheesy to me.
I think the best things races can do are provide a weapon or armor proficiency you really want that your class won't be providing, grant advantages, and boost your ability to survive (as so few class features contribute to actually doing better damage in combat).
Unfortunately humans do feel a little weak in the game, especially since half-elves just offer the best parts of Human (weapon/shield proficiency) with better additional features. I think as an improvement to humans, maybe their skill proficiency bonus should instead be the ability to choose a second background. This would still stick with and even define more the "human versatility" aspect while also giving humans the opportunity to pick up an additional proficiency and additional inspiration. Though, I suppose this is probably also a programming nightmare given that the game probably isn't built to check for multiple backgrounds. . . it would push humans up to a respectable level. I also think Dragonborn could use a little love maybe in the form of an extra ac for their tough skin.
Overall I think Lucky makes Halflings one of the best races, and an advantage on stealth and vs. frightened is a decent perk. Dueregar Dwarf is just as good with saves, superior darkvision, poison resist and two useful spells. Deep Gnome and Drow are on par and I think those 4 are the best of the best races. The next tier would prob include all the other elfs and half elfs.
