Personally I'm not a fan of 13 A sockets combined with USB outlets. The risk of unknown quality of 240 to 5 V converters that I can't turn off in a hurry and evict the smoking remnants is more than is gained by avoiding a few plug-in adaptors. A middle ground is n-way adaptors with USB included.
See bigclive.com's YouTube for examples.
Automatic light switches are nice in any room you keep moving in. Hallways and garages certainly, kitchens maybe.
Two or more way light switches in sensible places. Bedroom light switches by the bed and by the door, and make sure that you can reach the one(s) by the bed without getting up. Our house had the one by the bed in the main bedroom 1.5 m off the ground and 0.5 m from the bed, so too far to reach without just about getting out of bed, and it was on her side, so I often found it easier to use the one by the door. Now there is one each side of the bed, 0.8 m off the ground, 0.2 m from the bed, which can be reached while lying down.
You can never have too many 13 A sockets, or is that stating the bleeding obvious?
Power for cupboard lighting.
The Honeywell remote / computer controlled radiator valves are good, if spendy. They can be fitted later with ease, on the bases of cheap thermostatic valves.
Underfloor heating is nice and if you are ripping any floors up, it isn't much extra work.
Make sure that you have generous cooker and shower electric power supplies even if you currently have gas cooking and water heating, just to keep your options open. Similarly 30 A car charging cable(s), even if you don't put any socket on the end as the tech is changing so fast.
