The flying in AltspaceVR is a great example of good intuitive flying. My organization has been using it for meetups. There are two ways to fly, one is by turn on Fly, looking where you want to go, and pressing the thumbstick forward. Also, there is something called the flightstick that provides very precise movement (you have to spawn it from the menu). FYI, flying does not work in all environments, but will work in your home environment in AltspaceVR (which is owned by Microsoft BTW).
