Love your title
This looks like a solid cutting program. You said it's ok to throw some ideas at you as per the pm, so here's my .02.
Switch your back day to earlier in the week. You're scheduled to do deadlifts on Thursday, then on Friday you're going to attempt some A2G Squats and SLDL's! Other than that, since you're cutting, 5 days in the gym isn't a bad idea.
I also think you did a great job overlapping your muscles worked. Doing CGP for "triceps day" also works the pecs.
One more idea to throw in the mix. You could do a more "undulating" approach if you feel the need. Everything doesn't need to be 8-10 reps. Nothing wrong with doing power movements such as bench, squat, and deadlifts in the 3-5 rep range. A goal of yours during a cutting phase is to maintain/increase strength. So throwing 3 sets of 3-5 reps for those power movements, and keeping the rest 8-10 with the occational isolation exercise of 15 reps is a decent idea IMO. By isolations at 15 reps, I'm referring to stuff like cable crossovers, side laterals, pressdowns, ect.
