One other thing that I don’t think been mentioned is “Idle creep”?
When you come to a stop at traffic lights or crawling in stop start traffic if you take your foot off the brake the car will start creeping forward so keep your foot on the brake until you want to move forward then pop over to the accelerator and away you go.
Some cars have “auto-hold” built in with the likes of VAG cars that hold the car at stop for as long as you like and until you press the accelerator but many including the KIA I have now, the auto-hold only holds for two seconds to prevent the car rolling back when travelling in an up hill direction and gives you a very short time to get your foot off the brake and on to the gas.
