This is a neat chart that I found on Reddit today. If you go to the /r/DND reddit you'll be able to find it too, or just click the link here.
Effectively, Curse released the numbers for Race/Class combinations users made in D&D Beyond's first month. How does your character stack up? Are you a common build? Not so much? If you are common, don't let that make you think your char is generic or cheap. All things are trope, and it is how you execute that matters. Also, synergy leads to certain builds. There is a reason you have more Elven ranged characters than melee, and that reason is +2 dex among other things.
I was surprised that Critical Role didn't result in more Gnomish Bards, but beyond that the chart isn't too surprising. Though, I suppose if you wanted to go with the most unique character you'd need to make a Aasimar Ranger. Only 60 of those were made, though that number may have gone up as people seek out the rarest of the rares.
