Welcome.
What are your current working weight numbers looking like, and how have they been progressing recently?
Although you didn't list specific rep schemes, your program setup looks reasonable for now. That said, for powerlifting purposes you might end up needing a 3rd bench session at some point. I've also found that as people get more experienced training the bench, TNG and paused work tends to converge a bit (e.g. the difference between my 1RMs paused and TNG is only like 3-4%), so don't sweat the paused bench goal. I'd also consider exchanging your Monday BB rows with Friday's chins, so you don't have as much residual back fatigue going into DL day on Wednesday.
And although I understand your dilemma, I'm not sure cutting 8 lbs then gaining 11 lbs in 10 weeks is going to be productive (or worth the effort), particularly as you approach a meet with a 2-hour weigh in and some specific performance goals. Since you're still well within the 231 weight class, you might be better served to just hold steady where you are for now so you don't have to stress about the weigh in, nail your first 405 squat, then go into something of an "off-season" period starting with some higher volume training, smart conditioning work, and attention to the macros to facilitate shedding some BF. Just my $0.02.
