I just remember an idea I have for a fun "challenge" similar to what you're thinking. I want to make a Lizardfolk Monk. I'd be forced to start with a +2 Dex mod which is not very good for a Monk, and I'd probably spend my first 3 ASIs bumping Dex, but I like the idea of a Lizardfolk Monk that doesn't use a weapon, but bites a lot and has a mean tail whip lol. I'd start with 14 Dex, 16 Con, and 16 Wis. Just a thought.
Lizardfolk monk is actually quite strong, particularly early on, when their unarmed attacks do 1d6 instead of 1d4. And +2 con is great for everyone.
Something to consider when trying to make a bad choice is that small PCs get disadvantage with H weapons. So gnome barbarian with Great Weapon Fighting aint great.
There is a goliath rogue in my group.
