Room to be Rewired - Recommendations?

I am just about to have a major refurb on one of my rooms which will mean all new electrical wiring, lights and switches.

Previously, I installed Shelly 1PM’s in the light switches which worked well, but wondering if there are suitable (UK) Smart Switches and Sockets I could use; ideally WiFi. What I need are: -

Single Way one gang Light Switch for LED Lights
Single Way one gang Dimmer for LED Light Switch
Outdoor double-gang 13A Socket

Any recommendations or am I best in using the Shelly’s installed in the back-boxes ?
