Question Paris to Como: Best Stops Along the Way?

We're planning a 10-day trip starting in Paris, staying there for 3 nights, then heading to Como by train. We're hoping to make a few stops along the way to break up the journey. Does anyone have suggestions for must-see places or hidden gems between Paris and Como? We're open to anything from charming small towns to scenic spots that are worth a detour. Also, any tips on train travel in this region would be super helpful!
