Wife’s Inheritance Plan

My wife inherited just shy of a million dollars from her mother. We’re both in our early 40s and we’re chugging along just fine. Because her mother was retired with minimal expenses, her mom had all of the money in CDs and was living off the interest, even with the lower rates of recent years. I’m of the opinion we should move a large chunk of the money into a low fee index ETF and let it grow for the next 20 years. She is fine to keep all of the money in various CDs and just keep re-investing the interest. Can y’all help me with simple, clear, easy to grasp, reasons to convince her why in our situation, it makes sense to manage the money differently than the way her mom did since her mom was in a very different life situation.
