Control fanlight with both remote and switch
The receiver for the remote needs power to work, so you can't fully control it with the switch and the remote.  When the switch is off, the receiver will not have any power so it can't turn anything on. So, at a minimum, the switch can turn the light off, but in order to use the remote, you would have to turn the switch on.

Another possibility is to not use the included remote and instead power the fan with some "smart" switches that can be controlled with their own remote.  Doing it that way means the switch on the wall "is" the remote, so you can control the fan and light two ways.
