This probably answers both of your questions at the end:The way I'm reading the chart, ~6.5W's for 1.8GHz and ~7.39W for 1.9GHz. Although there is mention that above 1.6 GHz, there's this observation that it's getting hot enough for power consumption to noticeably further climb over a minute. So for towards the right end of the graph, I'm not sure if the numbers are for pre-heating up or post-heating up. Actually, probably post-heating up, because a bit later, there's an estimate of ~1.48W per core at 1.8GHz. Multiply by 4, that's 5.92. Then there's about 10% increase from there to get to ~6.5. That seems like a plausible difference between pre-heating and post-heating? In that case, maybe ~6.7W for 1.9GHz pre-heating... not that it makes much difference if that heating period's only a minute.
~3.5W for CPU + RAM in typical portable, yea.
The approach I was thinking of was to focus on the difference between docked and undocked, but that's lacking two components: the screen's power draw and exactly which profile the undocked Switch was using for Breath of the Wild in the Anandtech article. If we set docked to 11W and undocked to either 7.1W (min brightness) or 8.9W (max brightness), then the difference is either 2.1 (max brightness) or 3.9W (min brightness).
CPU and wireless should be the same in either state, so ignore them.
Joy-cons are assumed either already charged or not even attached, so ignore them too.
I'm assuming that storage is either not in usage while testing either state, or storage is used, but equally so, in both states, so I'm ignoring that too.
Typical ram difference between the two modes is about 1/3 of a watt? I'm assuming that the profiles setting RAM to 1331.2 MHz are more commonly used than the 1065.6 MHz profiles. 2.1 - ~0.33 ~= 1.77 (max brightness) or 3.9 - ~0.33 ~= 3.57 (min brightness)
Am I missing anything else? Until then...
1.77 = (docked_GPU_power - undocked_GPU_power*) - (screen_max_brightness_power)
Or, 3.57 = (docked_GPU_power - undocked_GPU_power) - (screen_min_brightness_power)
*caveat is, within the three profiles that set RAM to 1331.2 MHz, the possible GPU clocks are 307.2 MHz, 384 MHz, and 460.8 MHz.
...but can it be whittled down? Was the 460 MHz option added sometime later?
Switch's 'boost mode' tested: what is it and how does it work?

Originally it only had the 307-384MHz profile, seems like around 2019 or so the ‘boost mode’ was added to the switch that had the 460MHz profile added into the mix.
As for figuring out the GPU, we might need the help of a person where this might be up their ally.
Paging @Jersh on what the battery life of the Switch when running docked clocks in portable mode. With Max brightness and with min brightness if possible?
This might give us more information to probably extrapolate from.
Edit: so apparently first party games had the 460MHz clock since the start.
