Fighter with a decent dex, light/medium armor, a bludgeoning weapon and the criminal background (Deception, Stealth, Thieves Tools, Gaming set) should do it. Hell, add the Tavern Brawler feat and your all set!
All set to be a slightly sub-par Fighter, sure. I think that Minigiant was hoping for a Fighter who swapped abilities out to actually be really good at being a Thug, or a Rogue who could Sneak Attack with STR weapons.
The latter is pretty much a must for 5E as time goes on (even if limited to Light STR weapons) - too many Fighter/Rogues and Rogues in fiction who fight that way to ignore, imho.
