I'll give you some basic input on what you are trying to accomplish and outline some best practice.
1. Speaker cabe is also cheap, architectural speakers can allow you to have much more even coverage for sound in spaces over a single speaker stuck in the corner. Even if you don't install them all right away, once you have one pair up and running in say the Kitchen, you will definitely want to expand upon this.
2.I'll start out by saying, if you speak to any automated home installer or AV Tech, they will ALWAYS prefer wired over wireless. As much as WiFi has improved over the years, you are never going to have the exact same reliability and security of a wired system. With streaming being commonplace now, built into all Media devices and TVs they spend a lot more time using internet traffic.
I would recommend running 2 CAT6 and a coax to your TV locations as a minimum.
As you are gutting the property, it is the perfect time to run cables everywhere you might need them, TVs, Office, PoE CCTV, etc. Not to mention perhaps a local Jack in Kids bedrooms where there might be a desktop or games console.
This will greatly improve your overall flexibility and reliability. Cable is cheap, and with the walls stripped it's the perfect time to do this.
If you need more ports than your router offers itself, an Ethernet Switch will expand your ports for very little cost.
3. I'm not a expert in automated lighting, but there are many products on the market from Lutron, KNX, Crestron, Loxone, Control4 etc. Each have their own merits, and most of the systems have drivers to integrate with consumer voice assistants.
4. PoE cameras would be best. Again, for reliability, and to have a central recording NVR. The camera, as the PoE suggests, takes power and data over a single CAT6 line. Depending on how many cameras you are looking for, kits can be competitive, from 4 up to 32 cameras. In industry, the generally preferred brands are HikVision and Dahua. These do have apps for streaming to a mobile device, or if you are installing a full-blown automation system, there are drivers to integrate with your chosen controller.

I'm just not sure if something like Alexa or Google home would be fine for my needs or Control4 or Savant for the network? The following is what I'm looking for.
Really would like voice control of most of my lights and TV's.
1. Speakers in living room, kitchen, gym and outside. Why would one go for wired over wireless? Wireless seems to make more sense. Why put speakers in wall and ceiling then stuck with placment. Don't really care about audio reciever. In current home have Sonos and happy with it.
2. For TV's I do think hard wired cat 6 is the way to go. Guess I can go right from router to TV with cables.
3. Lighting control. Would like to have voice/scene control of lights in rooms. Not sure the easist least expensive way to accomplish this.
4. Security cameras. Right now have Nest and it's ok. Why would hard wire be better over wireless. Can a wired system still be viewed via an app?
I hope some of this helps address your questions, I know there are others on here with more in depth knowledge of specifics in lighting etc.
Budget for the "brains", lighting, speakers and cameras is about $2-3K. Any feedbak would be great, thanks.
