Heya,
So you just want a fast to AF lens that is silent to use with Live View AF? You don't need EF-M lenses for that, just most of the STM lenses basically are what you can take a look at. The 18-55 STM for example is dead silent and fast to focus. The 22 STM, 40 STM & 50 STM for example are slower to focus and noisy when they focus. Totally different STM motors. There's also the 18-135 STM and the 24-105 STM, etc, not sure how they report for speed and sound of AF motor, hopefully someone else can chime in on that.
Very best,
