What really helped with my bench was increasing my overhead press. I never trained it for the first year or so and whenever I trained shoulders, it was dumbbells, machines etc. I really struggled to get to 225 bench but when I started doing ohp’s and got stronger at them, my bench shot up and I finally got 225. So maybe try that. Also, gaining weight really helped my bench.
I would recommend doing a top set 1-3 reps(RPE 9-10) and the drop the weight back so you can do 3x6-8. I also found that lowering my intensity and volume really helped too. You’ll get 225 in no time cuz ur way older and bigger than me.
