Update: I'm pretty sure I've found it. Going to answer my own post so anyone else looking for this answer doesn't have to re-invent this particular wheel.
I started looking at the switch under my microscope, searching for ''any'' usable markings. On the broken plastic area I can make out the number '13' though I'm not sure if that is a partial number, but on the rear of the switch was the payoff: 'HIGHLY' - which is a Chinese electronics manufacturer that specializes in switches.
Measuring the size of the switch at on the side (horizontal axis when facing the 'front' of the power switch) measured at roughly 6.5mm, hard to be exact since I'm having to eyeball things a bit (it's a tight fit and I can't quite get the jaws of my caliper around the part). Once I found the brand name and started looking through their products, I found one that visually looked right in the 'Tact Switch' category and found 'Model：TP6152 Series'. This has a couple different physical models and then different LED color options. These switches contain 2 different LEDs to provide 2 color options: the Optiplex uses (I believe) White and some Yellow variant - the spec sheet offers either Yellow or Amber, so I'm honestly not sure which would be correct. I'll also ''probably'' need to take out the switch and manually power the LEDs to see which LED is which color.

Note: it seems neither Mouser nor Digikey carry HIGHLY brand... finding the part may be a chore.

Edit: oldturkey03 found a brand from a prior Optiplex Micro that Mouser does carry, should someone else run into this in the future, this is currently looking like the way to go since I'm having a heck of a time sourcing the HIGHLY brand part.
