Legend
Their adventurers are people who come from a small town that most folk outside of it don't even know is there, or who grew up in a settlement of another race, where they were the Small Folk amongst bigger, louder, less lucky, less likeable, folk.
One problem might be.... that's gnomes.
Gnomes are a small race that come from a small town that most people don't even know is there... because they hide the town with illusion magic and mostly live underground.
Halfling towns and their large farms and their orchards go unnoticed because.... Luck?
The "secret enclave of small folk no one knows is there" is just done far far better by Gnomes
However, the iconic halfling culture doesn't have standout warrior traditions, or magical traditions, they just have folks. Their warriors are bounders whose training and gear is very practical and who are just John the Bounder. Their wizards are hedge wizard nerds whose magic is probably most practical with some broad utility up their sleeve, and most magic they'd use to defend their town is magic that was invented for something other than battle, or at least can be used outside of combat.
Which could also be an entirely human thing. What about being practical is a halfling thing over a human thing?
Maybe it is different for other people, but this just doesn't feel fundamentally different than how I would describe certain "salt of the earth" trope humans. Maybe it is because I am an english major and so the "good old farmer" is such a human trope for me that I can't escape it?
Honestly, nothing screams human to me more than these agrarian, simple but practical, good-hearted folk, tropes.
