The tubular bulbs in the chandeliers, the shower light in the upstairs bathroom, the closet lights in the upstairs bedroom and basement, the bathroom vanity light in the basement, and the recessed lights in the first basement bedroom you showed had incandescent bulbs in them. Nice to see that! It would had been cool to see a fluorescent light somewhere too!
Or it’s setup for the ceiling fan, one switch for the light and a switch for the fan, since that fan has a remote, only one power source is needed for the remote receiver, and the other switch is disconnected in the fan box, therefore It doesn’t control anything
