Cardio before or after session/On “rest” day ?

Simple question, do you perform cardio before your AM sessions or after? or do you perform cardio on rest days? What is best in your experience?

I’m currently performing my cardio (high intensity short interval sprints 1on1off)on the morning of the days I have my AM sessions. Usually a few hours in between. I also lift on AM rest days. I’m looking to experiment, but I would imagine it would be better to do cardio after AM session?
