Google hub, just forget this get a real hub dont be stuck in an ecosystem. Home Assistant is the free one that is generaly suggested.
HS220 Don't get wifi for anything you have any other choice for. These are things the should still be around and working in 25+ years. I suggest z wave, zigbee, or thread/matter here. Even sooner how long do you think TP-link can be trusted to keep thing's going they have allready broken the local API once.
Aqara door/window sensors, why on a new build would you use these battery powered ugly things? Hard wire cheap alarm sensors it cost me next to nothing to do when I built last year. It's trivial to integrate the real UL listed alarm so you get money off your homeowners and alarm.com etc can monitor it for a few bucks.
Reolink is fine suggest using frigate for the NVR to get all the ai object detection, just mke sure to wire them all.
As to outside lighting I love having dimmers on my exterior lights lets them work with the accent lights to give me plenty of light for a party but also having the WTF is that out in the woods insta daylight.
