There is not one single recipe for every situation. Your question needs some serious rethinking.
For a trainee pilot: do what the FCTM tells you to do, and finetune it as you get more experienced.
For experienced pilots: fly the aircraft
Most of jets have the main landing gear well behind the center of gravity, thus the landing gear is behind the pivoting point. So you can easily drive the landing gear onto the runway when pitching up close to the ground.
Even with autothrust you will need to vary the height at which you put the thrust levers to idle.
Oh Yeah and Vapp with manual thrust = Vls according to airbus in zero wind.
