//You simply project your vector onto the normal and subtract the result from your original vector. That will give you the projected vector on the plane. If you want to project a point to a plane you first need to calculate the relative vector from a point on that plane.

 Vector3 planeOrigin;
 Vector3 planeNormal;
 Vector3 point;
 
 Vector3 v = point - planeOrigin;
 Vector3 d = Vector3.Project(v, planeNormal.normalized);
 Vector3 projectedPoint = point - d;

body.interpolation = RigidbodyInterpolation.Interpolate;

don't parent target to camera that follows it, especially if target or camera is physics driven

if target is physics drive, use fixedUpdate on camera
