Ideally I'd want to either clinch and dominate that range with dirty boxing or takedowns, or stay on the outside using footwork while peppering with jabs and kicks (such as teeps, obliquethe occasional straight left. I might use the uppercut to punish them moving into the clinch, and leg kicks)but primarily I'd want to rely on angling out rather than winning the dirty boxing fight.
To speak to the mindset behind this kind of question: this theoretical approach is rather useless. Firas Zahabbi said, "I can’t tell you the game plan. I have to spend months training you in the game plan." To take his point generally, a properly trained fighter doesn't sit and think about their strategy. They practice the strategy in the gym against trained, resisting opponents over and over. They don't think, they know exactly what they'd do against a bigger, stronger opponent taking strategy X because they've already done it in the gym.
If you box and wrestle with these tactics regularly--whether that boxing and wrestling is at wrestling, or judo, or boxing, or Kyokushin, or whatever gym that spars--then then you'll know exactly what approach you'd like to take. If you don't train, then being told won't help, because you won't be able to execute it.
