Thank you for your quick response and for finding the valid link.
The workaround in the link is the same workaround I had already considered, but I was curious if there were any other workarounds.
I appreciate the information on the trigger, though I don't think I will go that route.
Posting solution to avoid any linkage issues in the future:
Identify the field that you want to send a notification. (Field 1)
Identify an unused OOTB field that can have field change notifications. (Field 2)
Create a field change notification when Field 2 is populated with the desired value.
Create a field change rule to populate Field 2 when Field 1 contains the desired value.
