You should use code fences so you don’t have to fiddle around with the item definition formatting.

So for the common power control part of a group endpoint, it usually better to use PowerController over ToggleController, unless you want to request “Turn on/off Fan Power”. The reason is that with the latter interface, you need to specify the actual functionality name, while with the former, it is consider the default power control of a group endpoint. Also the @Setting.Fan asset id doesn’t exist.

The below changes should work as you intended to use. I updated the endpoint category to fan and also brought the lights in the group endpoint, since it is part of that device, using a ToggleController interface.

Group Fan "Fan" {alexa="Endpoint.Fan"}

Number CookerFan_Control "CookerFan Ctrl [%d]" (Fan) {alexa="RangeController.rangeValue" [supportedRange="1:3:1", presets="1=@Value.Minimum:@Value.Low:Lowest,3=@Value.Maximum:@Value.High:Highest", friendlyNames="@Setting.FanSpeed,Speed"], mqtt="<[mymosquitto:home/cookfan/fanstate:state:default], >[mymosquitto:home/cookfan/control:command:0:f0], >[mymosquitto:home/cookfan/control:command:1:f1], >[mymosquitto:home/cookfan/control:command:2:f2], >[mymosquitto:home/cookfan/control:command:3:f3]"}

Switch CookerFan_Power "Cookerfan Power" (Fan) {alexa="PowerController.powerState", mqtt=">[mymosquitto:home/cookfan/control:command:ON:f1],>[mymosquitto:home/cookfan/control:command:OFF:f0], <[mymosquitto:home/cookfan/fanstate:state:MAP(fanonoff.map)]"}

Switch CookerFan_lights "Cookerfan Light" (Fan) {alexa="ToggleController.toggleState" [friendlyNames="Light"], mqtt=">[mymosquitto:home/cookfan/control:command:ON:l1],>[mymosquitto:home/cookfan/control:command:OFF:l0], <[mymosquitto:home/cookfan/lights:state:MAP(onoff.map)]"}

Thanks Jeremy, that worked a treat.
I also went back to my question to include the proper code fences in my question.
These are the manual controls which are now automated:
