Provided simply for general interest in world-building:And I acknowledge, Eberron, a setting known for rewriting basically everything and some very good worldbuilding, did something interesting with some of their halflings. You also mention Golarion... which is a Pathfinder setting? I'm not really sure what Pathfinder has done with halflings, never played, never really considered it. I know Golarion has some interesting art and lore, but I also don't see what they really have to do with DnD, except to show that a literal DnD clone kept DnD races like halflings.
Golarion did do some interesting things with halflings. Halflings in Golarion have been enslaved many times in their history, and a large proportion of them remain enslaved in the more evil nations. At least two of the halfling iconic characters have this past dealing with slavery as a major part of their backstory.
Free halflings in Golarion are very involved in trying to liberate their brethren, and there is a fair amount of lore on the Bellflower network, an underground network run by halflings spiriting slaves out of Cheliax and Katapesh.
This take on halflings supports why many halflings would be rogues (as this is a very congruent skill set for Bellflower agents to have) or bards, and provides multiple hooks for halfling adventurers.
Of course, this is a major change from the way halflings are portrayed in the PHB, and I suspect that the people who like halflings as is probably would not like this very different take on them (and I can understand that).
