Increase your frequency, figure out what works best for you in terms of form, and hammer accessories. Big triceps and big shoulders obviously will help your bench, but also a big back/traps since that’s basically the platform off of which you bench. Try to milk as much weight as you can from a linear progression program, then move on to something less simple once you cap out on that.
There’s no real formula to a big bench, some people are just naturally better at it than others and will progress faster. Just gotta stay consistent with the programming and the numbers will come.
@OP - increasing your body weight might also help. We have similar numbers aside from the bench... I’m also 5’9 with long arms, but weigh closer to 195 with a 550ish dead, 500ish squat, and 405 bench
