Great write-up, thank you OP!
I'd like to suggest an addition: I often get the question: but will distro XY run on my device? Then I suggest to boot from an USB stick and try everything in a live session without installing anything. (And if people are just curious how it will look and feel, I recommend https://distrosea.com/)
Also, I miss the mention of Cinnamon. Mint is very popular as you have already said and the "flagship" version comes with Cinnamon.

I can't code either but I'm supporting new users in selected forums on a daily basis and I volunteer at our local linux event once a year.
