Not that anon but I had similar problem with height, in VRChat I couldn't reach the floor even though I touched it IRL. In Beat Saber everything was too low as well — when I hit that height calibration button it got set to 2.2 meters. 
I set up guardian in Rift S again, and still couldn't reach the floor even in Oculus home. So, there's a setting in steamVR too. I'll look into it.
