I don't think there is any recommended values for the Field Of View and distance. It's mainly a personal choice.
In average, it has no impact on the frames per second.
It's all about finding the good balance between being able to read gauges and seeing enough elements of the scenery.
If you can not rotate the camera easily, you might prefer a wider FOV.
For me, I have a Full HD 21" screen, 1 meter away from my eyes, and I like to set the FOV at 85°. Sometimes I chose 60° instead.
You may also find it convenient to move the camera backwards, adjust the zoom and save the view with ctrl+numpad. You can then call the view with the numpad key you used to save it.
Hope this helps,
