Your electrician will advise but you really don't want the outside stuffon the same RCD as the house sockets (any fault outside due to damp or small animals would potentially mean no power in the house).
Not sure if RCBOs are available to fit that board, other option is Henley blocks & garage CU to control outside stuff.
Depending how posh your shed is going to be (escape room from the kids maybe) consider chucking a duct in the cable trench for data, alarm etc
