Get-WMIObject Win32_CDROMdrive | Select MediaLoaded does a great job of telling me if there's a CD loaded into my CD drive. It returns this:
MediaLoaded ----------- True
My problem is: I can't figure out how to evaluate this output as boolean "True" or "False". It always seems to be "True" even when the return text says "False".

You don't expand the property, so your Select-Object command gives you an object with one property with a boolean value instead of the actual boolean value. Since PowerShell interprets non-empty/non-zero values as $true you're getting the behavior you observed when you use the object in a boolean context.
Change this:
... | Select MediaLoaded into this:
... | Select -Expand MediaLoaded and the problem will disappear.
