I have a 2011 Avalon, 3.5L V6 auto w 120K miles. Runs fine, good power, 25-29 mpg still. Has had excellent maintenance BUT it’s still on the original spark plugs. How do I know when to change them?

Go by the recommended Toyota service schedule (I believe 60K miles). IF you don't have the owner's manual, you can download a new copy from Toyota's web site.
Here's what they recommend for your car (don't forget to check your floor mats!)
