If you do Stronglifts for two months that will get you a foundation in powerlifting and adding weight.

Then you calculate your theoretical max for each lift on this site: https://strengthlevel.com/one-rep-max-calculator

Then plug those into 5/3/1. I can't say enough good things about 5/3/1 - it gives you an elegant and consistent approach to PRs.
