This movie shows how my thinking Particles confetti asset works. I'm inspired by the bunch of confetti R&D movies recently :-)

With calculating dot product between particles Z alignment and moving direction, I can get value from -1 to 1. When value is close to -1 or 1, I add strong friction. At the same time, I add some x and -x position value according to dot product's value. Y and -y position also. In this way, particles can move from side to side.
This version needs some modification. I'll provide my setting when everything has been perfect :-)

Hmm…it looks like things are taking a while to load. Try again?
