A Pantograph Boxer. Fighter with a focus on repositioning annoying enemy gunslingers for Reactive Strikes and locking them down with reach.
Do any of the backgrounds in the Player's Guide spark any joy? AP backgrounds often come with plot hooks, so they're probably a good idea. Outlaws of Alkenstar is also fairly urban, so you can get a bit Prohibition-era with your concepts, too
Okay some actual ideas:
Fleshwarp Investigator, Framed in Ferrous Quarter background - a hardboiled, laconic private eye, whose efforts to find missing persons from the Ferrous Quarter led to their being framed for murder, and now they're laying low and looking for an opportunity to prove their innocence, and take down the crooked shieldmarshal who framed them
Halfling Rogue, Snubbed Out Stoolie background - a former infiltrator and informant for the shieldmarshals, this cheerfully unflappable rogue did good work infiltrating gangs of bootleggers, gun runners, and assassins, with their talents for appearing unassuming - as well as a sharp pair of ears and clever fingers - but now their former colleagues are out for their arrest. They're gonna need every scrap of cunning - and more than a few of their criminal connections - to get even.
Talos Champion (Justice Oath), Guard or Night Watch background - a would-be shieldmarshal too honest for such a corrupt captain, this silver-veined stalwart was both fired from the force and accosted by their former colleagues in a dark alleyway that very night. Deciding it would be too risky to return to their former lodgings, they instead attempted to rely upon the generosity of an old friend (old friend in question could maybe be another PC, or perhaps the starting questgiver)
Ancestry for all of these is vibes-based, none are particularly optimised picks (though a Filcher's Fork is a pretty good rogue weapon)
