Home office & connected home setup

Hi guys, need some help please

just refurbished house and run cat6 cables everywhere

We've got fibre to premises being installed soon too

so as we run a home office for 2 people, also home school getting the network setup is crucial. 
I want at least a 24 port Poe Ethernet switch and a 4point mesh Wi-Fi setup. 3 of the 4 access points for the mesh Wi-Fi need to be ceiling mounted (already pre wired cat6 so need to support Poe) 

can anybody suggest what equipment is needed as the new orbi doesn't look like it has ceiling mounted variants. 
ideally like Wi-Fi 6 enabled as my new laptop and phones are compatible. 
the network switch will have Philips hue lighting hub connected as well as smart heating, and nest smoke alarms. CCTV is Poe+ and then all tvs and game consoles have cat6 run to them. 
As we were refurbishing the house I took opportunity to make the house as connected as possible so would like to get the setup right from the beginning so any advice gratefully recieved

cheers
