Congrats! I've been there. If I can offer advice, it's easy to overdo it. You're on the right track, focusing on volume.
Tempo work did well for me - it is self limiting in terms of loading, and you can really focus on form. I liked 3-0-0 squats (3 seconds on the way down, no pause, normal speed on the way up) and 2-0-2 Romanian deadlifts for my recovery.
