- take the train back to Munich and fly home from there

As the OP will already have done the scenic train journey on the way down there is no real need to do it a second time - unless he wants to take a different route and see different scenery. And flying home from Venice would give him an extra day in Italy.

If I was in the OP's shoes I would probably only do the train journey one way, and then fly home from Venice (i.e., book an open-jaw flight)
