You’re already playing on easy mode mane no worries and cardio’s not even a determinant in successful dieting for body composition. Hakuna matata
Srsly tho depends how lean you are or want to get.
Especially on low carb and after a full session of lifting (which is pointless mind you) HIIT will start feeling pretty shit real quick. May end up being Medium IIT instead lel. If you can do it early in the cut go for it but when it becomes unsustainable switch over to LISS.
LISS is probably better for you if you had to choose one right from the start. Lets you go as long as you want without smashing you, burning however many extra calories you need to. In this way it’ll minimally affect your lifting, where you’ll need to keep intensity up to hold onto max muscle, and leave you feeling better overall during your diet.
Personal favourite cardio is to jump on a stationary bike and spin my legs at 100rpm until I hit enough time/calories. Put on an episode of your favourite television show and the time flies right by and you don’t feel the burn as much because you’re distracted by the entertainment.
EDIT: also fasted cardio is bullshit broscience to the max:
