As of ROS2 humble there is also read_points_numpy (see here) which would give you directly a 2D NumPy array. For example:
cloud = point_cloud2.read_points_numpy(
msg, field_names=['x', 'y', 'z', "intensity"], skip_nans=True)
Note that there also exists a read_points_list (see here) at least for galactic, foxy, and humble which would have simplified the code of the other answers.
