Home automation is the residential extension of building automation.
It is automation of the home, housework or household activity.
Home automation may include centralized control of lighting, HVAC (heating, ventilation and air conditioning), appliances, security locks of gates and doors and other systems, to provide improved convenience, comfort, energy efficiency and security.

Awesome thank you all guys for chipping in. So much to unpack here for an electronic guy who has no experience in networking and home automation.
I just spun up HA yesterday to get my feet wet and I can see how easily I can get tempted to rump it up with a bunch of smart stuff. Ideally, I want to use less internet connected ones (although I said IOT initially, but really mean smart devices which i can control via HA and don't ping home unnecessarily)
Conduit is a great choice, my mind struggles to assimilate how to leave the unpatched end of the cables/conduit at various sides of each room without building too many recess points. Or even how high to leave them from the floor.
Regarding conduits, perhaps I can run one to the corner of the windows for blinders, motion sensors and automatic windows (if I can find those)
Won't running a conduit to every power socket (3 per room at least?) might be a bit overkill? Apart then the computer corner power/ethernet and TV sockets would I need a conduit near bedside tables power points?
I see the point why switches in every room are a maintenance issue. However, these smart devices, would they saturate the network so much that I need direct cable from each of them to the server closet?
I am not planning to run a streaming device at the end of each. High Bandwidth TV/PC, camera cables should go directly to the server closet, but the rest hopefully will be
Have a look at this video:

Skip the ~7:00-13:30 section as it is not relevant.
In the last segment, he goes over a conduit run from the service entrance. However, I would be running strapped-down rigid conduit since, when pulling cable, there is potential for it to flex (it will absorb the pull force, rather than the force acting on the cable only). His endpoint in the attic area is fine for single-floor homes, but for multiple floors, you will want to run those all the way to the destination.
I would also run conduit for all the wall jacks instead of bare cable.
One thing you can consider: Those new LED puck recessed lighting can double as ceiling access panels. You can end some conduit near those areas. A lot less work to fish wires if you already have 75% of it done
Here is another good reddit discussion "Deciphering what "run conduit everywhere" means for a home remodel"
If you use a single, low-cost wifi router, or your ISP's CPE device, it may, yes. This is why most people are talking about adding WAPs (wireless access points), which are not routers by the way, they plug into the router (ethernet cable, PoE-powered usually) to "extend" the reach of your wireless and add capacity.
Who's to say in a few years you even WANT to connect these devices to your network? What if they aren't ethernet at all but can still run over twisted pair cabling? Or maybe you end up wishing you had some fiber, or something else?
Independent runs isn't about saturation, these aren't gig traffic devices. It's about management and flexibility. There are just things you can't do with a bunch of cheap pocket switches.
