I don’t see either of these suggested anywhere in the thread and they are both very usable solutions to not being able to zoom in VR. I use both, plus the focus, and I’m totally happy with how it’s working for me.
1 - set up some custom instrument cameras pointed at the things you need to see often at a distance you can read them - I set up one pointed at the gps/fmc, one at the overhead, a couple on different angles at the pedestal, plus whatever else I need. Changing to the custom cameras leaves me looking straight at the gps, then I can cycle through the others, then pop back out back to where I was. Has to be done for each plane but we had to do that with chaseplane anyway and we tend to stick to our favourites so not a big deal.
2 - You can’t zoom the VR cockpit camera but you can move it. I use a hat switch to translate the cockpit camera left / right / backwards / forwards which I use all the time, and the easily found arrow keys to increase and decrease the cockpit view height which I don’t often need, and when I’m done if I don’t want to put the camera back manually I just reset the position. Works brilliantly, especially to slide across to the right seat to look out of that window 
Hope this helps someone.
