Is there a place where you can see an overview of Queue usage? Maybe in the APM bundle? I'm looking to do a queue analysis to find the best place/time to schedule a new Map/Reduce. Hoping there's a visualization/report somewhere

The Script Queue Monitor page in the APM has Script Instance Heat Map at the very bottom of the page. You can change the date range, and look for any holes / quiet times

Awesome, thanks!

The SuiteCloud Processors Monitor has even more useful information broken down by time into line and bar graphs. I don't know if that page exists or works without a SC+ license, though.
