Choosing a laptop wasn't a bad idea, you just chose one that isn't designed around what you need.
I use a different NLE at the moment, but it would be a shame to waste the opportunity to use Resolve studio since it comes with the camera.
Resolve is generally among the fastest of the NLEs if you throw enough horsepower at it. It consumes a lot, but it scales well (far better than the Adobe's).
This Davinci eGPU boasts brining “High-end desktop graphics processing to your laptop”. I didn’t see mention of “...depending on the format”.
It was high end once. Now it's just old. Not that it was even competitive when it WAS high end, though.
However, there are plenty of options out there that will allow you to choose a more modern card like a Vega 64 which is almost as fast as an nVidia 1080, and for things like color grading and Fusion will in the long run be a better option.
Resolve works pretty well with eGPUs; I've been using it on an HP Spectre x360 with an eGPU housing a 1080Ti, and ended up using that configuration to grade and render a feature film shot in 8K. It's not ideal, but it does work. Sapphire didn't like that configuration too much though; it crashed my renders in a few places (consistently enough that the only option was to remove the effect from those clips).
My system is CPU gated. It's an ultrabook (for budget reasons) and an older ULV quad-core model (15 watt TDP), so it can't saturate the eGPU because it can't decode the raw datastream quickly enough to give my GPU a workout.
You'll get a bit better performance since your machine has a 45-watt version of the same processor, but it's hard to predict a percentage.
