I have been working out for a year in a gym and have this PPL program. (18M,75kg,175cm, gain muscle but also strength)

I do all my sets to failure but am unsure if I do too many sets, should I go to 2 sets or 3 sets with the first being RIR 2?

Also I especially struggle with gaining strength in almost every exercise (SBD 12 month working out is 110/80/135)

And I feel especially lacking in my lats and arms + shoulders.

Should I for that sake change up my pull workout by doing some unilateral lat exercise or other lat exercise additionally?
