I went the Lutron route, and am very happy with it. The only two caveats are that it doesn't allow you to control the speed or direction of the fan, which is a minor annoyance, but more importantly the Lutron app treats it as a light. So if you use the Siri command "turn off the lights," it will also turn off the fan...and vice versa with the "turn on the lights" command. If anyone knows a way to fix this, I'd love to hear it.
That said, I'm thrilled to have my fan finally trigger automatically when I'm away based on the temperature of the room (working in concert with the Elgato Eve) - it's going to make my birds very happy.
