I had a very similar setup in my previous apartment. I used a lot of battery-powered Zigbee devices for motion sensors, contact sensors, etc. and attached them using 3M command strips. I also wired up some Zigbee switch modules behind the light switches, so I could control all of the lights in our house. (This was way nicer and cheaper than using Hue bulbs everywhere.) I also had curtain motors, and a SwitchBot Hub to control air conditioners, etc. Everything was pretty easy to remove and take with me to our next house.
