Driving from Cortina to Venice - stops along the way?

Hi! My boyfriend and I will be driving from Cortina, where we'll be staying for 3 nights, to Venice, in mid-September. We have a rental car, and will be dropping the car off in Venice, spending 4 nights there, and then flying out.

I know the journey by car takes about 2 to 2.5 hours. Is there a particularly scenic route we can take, or anything noteworthy we should definitely stop and check out on the way? Maybe a place we could plan to stop for lunch? If not, we can just bomb through and have more time in Venice, but I love the countryside so figured it was worth an ask!

Thanks so much!
