Keep the weights heavy
Fat loss comes from the calorie deficit, not from switching to feathery pump sets. Keep training in the 5 to 12 rep range with challenging loads so your muscle has a reason to stay while you strip fat.
Keep the same heavy lifting and volume to protect muscle; the diet drives fat loss, not a switch to light high-rep work.
The biggest mistake on a cut is dropping the heavy weights for endless light reps, which tells your body it can shed muscle. Keep lifting heavy with the same exercises and roughly the same volume, since that heavy stimulus plus high protein is what signals your body to hold onto muscle in a deficit. You may need to trim a little total volume as energy dips and recovery slows, but intensity should stay high.

Aim to hold your 10 to 20 hard sets per muscle, but understand recovery is worse in a deficit. If lifts start sliding across the board, trim a few sets rather than cutting intensity, and prioritize the compounds.
In a deficit, protein rises in importance, so hit the top end near 2.0 to 2.2 g per kg. Combine that with 7 to 9 hours of sleep to keep strength up and recovery intact while calories are low.
