twojarslave is in a similar position to you, and has been an exemplary model of “what to do as a fat guy new-ish to lifting that’s trying to slim down while getting strong” - see his log here:
You look like you’re on a similar road. Keep working. I’ll agree that you should be fine in a slight caloric deficit for awhile. Let some of that poundage melt off you. Your lifts ought to go up at least for a bit yet, although eventually you’ll have to fight a little harder for the gains. Good luck!
