This one! 
That is a great little writeup, thanks for doing that! Getting through the installation with an Nvidia card is a common pain point we hear about in the forum, so those tips are very useful.
The only thing I would add for consideration is that using Optimus Manager is generally advised against because it can have undesirable behavior. Here is the âofficialâ recommendation for switching between iGPU and dGPU:

The article describes these disadvantages associated with Optimus Manager:
Common misconceptions and antipatterns
Quite often, software such as âoptimus-managerâ or âoptimus-switchâ is used instead of PRIME. Although they feature âhybrid modeâ, they also feature modes that exclusively switch to the dedicated or iGPU. Using these modes is an usually not recommended, because
- If your NVIDIA driver ever fails to load, your system will be unable to enter a graphical session
- In NVIDIA mode, the dedicated GPU is always used and therefore always turned on even if no software that could properly take advantage of it is running. The iGPU is much better suited for running low power common desktop applications.
- Switching modes requires logging out and logging back in or otherwise restarting X11. Meanwhile PRIME can be used without restarting X11.
@cavaughan my guess is Garuda will work just fine on the new laptop, but there is only one way to find out for sure! If you have any problems during the installation, go ahead and open a new thread so we can take a look.
