From my POE switch I see that it has allocated 31.2W ( self discovered POE 802.3at )
Each time I monitor it is ~ 10W consumption

I didn't measure the power consumption, but I was surprised at how much heat the AP produces in idle mode, i.e. without data being transmitted. This is probably around 20 W - too much for my area of application from an ecological point of view. I have therefore decided in favour of another slightly less powerful product.

For me it draws about 11-12W

I have not yet done that but I will. I plan to connect this Access Point (AP) to a POE switch which is only able to deliver 20W per port. My assumption is that 24W is an absolute maximum when the AP is active on all frequency bands (2.4, 5 and 6 GHz) and pumping data at maximum speed. If 24W is a worst case, then the average must be well below 20W, also because I don't know any use case (apart from speedtest, during a few seconds) that would max out the bandwidth of this wifi7 AP. To make a long story short, I do believe 24W is a worst case and the box should consume less in real life.
