I wouldn't think it is the work surface height that's so important, but the height of comfortably operating the tool, handling the tool, itself. Bending a little, to see the work being done, shouldn't be such a big issue, though it's nice to comfortably see your work. I wouldn't want to reach uncomfortably high, to grasp the saw handle/ grip. Mid-chest high, for that tool, is comfortable for me, at 6'.
I have a Delta sawbuck whose work surface is 35-1/2". Gripping the handle is about 8"-10" higher. It's comfortable for me. I still have to bend, often, to see what I'm aligning, before cutting. Table saws are 34-1/2", work cabinets/tables are 36". ... I bend all the time to see things, properly.
I have a French buffet that is 39". Mounting a miter saw on it would be, I think, uncomfortably high to handle a miter saw. That would put the handle/grip at least 12" higher. I am visualizing this might be an awkward reach. Compare this sort of reach with operating a RAS.
I'm with others in: Make a mock-up table and test a few heights that suit your reach, not necessarily what you can see, conveniently, as you work.
A comparison, somewhat, would be: Using a skill saw at 30-35" is much easier, and probably safer, than at 43"- 45". It's not seeing or aligning, for the cutting result, that's so important, but the cutting technique. The best cutting result would be a product of the best cutting technique.
Don't allow the tool, or its setup, to control you or dictate to you. YOU control the tool.
