Health baseline
A couple of moderate sessions a week, plus daily walking, covers cardiovascular health and does not interfere with strength or muscle growth at that dose.
Do 2 to 3 sessions of 20 to 30 minutes weekly for heart health; add more only to burn fat, without starving recovery.
For general health alongside lifting, 2 to 3 cardio sessions of 20 to 30 minutes a week is enough and will not hurt your gains. If you are cutting fat, add more low intensity work like walking to raise your calorie burn without much recovery cost. Keep hard cardio on separate days or after lifting, and do not let it eat so much energy that your lifts suffer.

When cutting, extra low intensity cardio like brisk walking is the easiest way to widen your calorie deficit without the fatigue and hunger of long hard running. Steps are underrated here.
Long, intense cardio right before legs can blunt your lifting. Put demanding cardio on separate days or after your lifting, and prioritize protein and calories so the added output does not stall your recovery.
