I think it would be more than slight.I think it'll help slightly, but I think being in the deficit is just gonna put you in position with minimal energy. I was on a 6-7month cut where i lost ~20lbs and got <11% BF and the drop in energy during my workouts was substantial. The day I started clean bulking again, it almost came back instantly. I think on a cut just being able to maintain your lifts is standard, aiming to really increase them I think will be VERY difficult on a cut (unless you're on newb gains or a teenager). That's just my experience
Your body is going to burn up the available glucose in your cells and blood, once that is depleted it will move on to the anaerobic energy systems.
The Glycolysis provides a higher level of energy than the anaerobic system, so that is what you'd want to be drawing from for lifting instead of expending it during the cardio phase which wouldn't require such a high short-term output of energy.
You simply get more benefit out of burning your glucose for lifting than for cardio, and not in a small way.
While I'm no expert on gym energy choices, I am an expert in Track and Field energy strategies.
