The GE fan control switch (3 speeds) should do very well to control the fan. Google Home or Alexa will take a little more work because those see the switches as a dimmer. Because of that, you’ll have to say “dim the ceiling fan to 50%”, or whatever. May people create a virtual device for each fan speed so they can then just say the device name without have to specify the dim level. Personally I just say “Alexa, dim master bedroom ceiling fan to xx%”, and that works just fine.
BTW, Wemo doesn’t have a switch to control a fan that I know of.
