The attached video gives the noise I'm hearing. It does come and go. I was thinking it was the tensioner or a pulley. But still not sure exactly what it might be. I don't want to just start replacing things. Thanks in advance for any and all help.
Instead of guessing, get yourself a mechanics stethoscope (cheap) & locate the exact source of the noise. You can also use a short piece of garden hose. This one is from Harbor Freight for $8 bucks.
I decided this morning to remove the belt and test like you suggested, and decided to just go ahead and put in new tensioner, idler, and belt. Still had the noise but now with part of it out of the way, thought I would look at the AC side of things, which then it hit me to turn off the AC, and yes the noise went away, thanks for help in getting me started.

I was hoping maybe the issue would now be with the AC tensioner and/or idler, but with the noise going away when turning the AC off, the belt is still turning so all the pulleys are moving and if no noise, that only means one thing, it's the AC compressor, correct? And that seems like a major job to replace?

It could also be the harmonic balancer. If the resilient layer in the HB is shot, it could emit a squeaking noise when under load, such as shen the belt is attached and driving the other elements, such as AC compressor, alternator, etc. Did you try using a short length of garden hose against your ear to find the source of the noise? Be careful where you place that hose, though.

Correct. When you turn off the A/C, the only thing that quits turning is the compressor.

You can also use a long screwdriver or prybar, place your ear on the handle end and touch the tip to possible sources of the noise. Works the same as a stethoscope. I've used this method countless times and it works great.
