Could do a 6 monk / 4 rogue / 2 fighter
This is probably my favorite class combo in the game.
Pick thief, now you have 2 APR, Two bonus actions for Flurries/Kicksnand Action Surge.
I have a mod installed that adds more fighting styles, including unarmed combat. That changes punches from D4'sa to D8's.
Still. I'd do this 6 Monk / 6 Fighter. 3 Feat selections and the fighter subclasses rock. Battlemaster is probably the best kit in the whole game, but Champion is rather cool for this. 3APR mainhand + 2 from FLurry of Blows gives a lot of attacks that can crit.
