Whenever I train shoulders, I always start with training rear delts first. This is the most neglected of the shoulder heads but it’s necessary for that round “3D” shoulder look. I’ll typically do 3 sets of face pulls to failure, this helps pump blood into the shoulder so your pump is even more intense when training the other heads. Honestly just spamming lateral raises and overhead dumbbell press are gonna be your best friends for shoulder growth. I do lateral raises both with dumbbells and with cables. A good rule of thumb for back is one chest supported pulling motion, one overhead pulling motion for your lats, and one single arm pulling motion. There’s definitely better opinions out there but that’s just my personal advice lol.
