What HIIT and ab workouts can support weight loss beyond a calorie deficit?

I lift weights 3 times a week. Push. Legs. Pull. I’m looking for more ab workouts, all over hiit workouts, and lower stomach fat. I’m trying to focus on an ab and cardio combination that I like without making it feel like a chore. But any opinion is appreciated. Reference I’m 26, 260lbs, 5’10 ft in.
