Home Network upgrades incoming

I hope to redo my network equipment before the end of the year. I am hoping to switch everything to UniFi. I already have the Cloud Gateway Ultra router. I am going to get 2 WiFi 7 AP’s 2 switches one network extender (this is just in case) and 2 flex mini’s. My whole system will then be UniFi from start to finish. I am thinking about getting a Raspberry Pi 5 to use Pi-hole and some other stuff on it.

This will all replace my aging Orbi WiFi Mesh 5 system that I am currently using in AP mode only with a TP-Link first generation ER7206.

Why am I doing all this because I want things in place for the next 5 to 10 years and not have to worry about my network cables or network equipment and I can finally do this since I can finally afford it.
