I'm 5'11" and have longer than average arms and still prefer the front edge of control panel for machines I build to be at 37-38" from the floor.
Probably more important for someone taller than average is where the marquee starts infringing on view.
I set the lower leading edge of those to be no lower than 4-5" shorter than me- so around 66-67" from the floor.
I am talking about upright style here.
Cabarets often have screen face at a much shallower angle and so could get away with a lower height marquee/top shroud without it being an obstruction.
But I prefer to not be staring in the direction of my feet while playing anything.
If OP really wants to beat this topic to death I can measure what I have built and post it.
