It turns out WD40 company also makes 3-in-1 oil. Refer to
http://www.wd40.com . The site does not label the product as a
"lubricant" or "water drier". But it does suggest applications such as
removing spots, etc.

That should be your first clue that WD-40 is the wrong thing to use. It's a
poor lubricant.
Someone told me to give silicone spray a try, so I might do that, but
thought I'd pose a question in here to learn when using one over the
other is better.

You should use neither. A few drops of 3-in-1 Oil (available at any hardware
store or home center) on each of the squeaky hinges will take care of the
problem.
