Ok I understand the technical reality you poin to, I just refer to the user experience. For a normal user, you probably won't notice that technically manjaro is not arch and EOS is. IMHO Manjaro breaks a lot and EOS just works and needs less manteinance.
Endeavour os was the great manjaro replacement for mw
The say zen is suspicious. Brand new and not really tested. Keep an eye on it.
Being a linux user for 23 years and a linux promoter and installer for newbies, I don't agree with so many of your recommendations and priorities.
Think it very thoroughly if you want kids

Asus went the bad way. Check out louis rossman vídeos about asus, héroes one of them. https://www.youtube.com/watch?v=NHQqKi9NcTs It is a company to be avoided. It went the non ethical way.
Snap is not good. Flatpak is.
I've tried many things in this situations (seeing other girls, distracting with alcohol/drugs, etc) but they all just seem to alleviate the pain when they just throw it under the rug for a while.
For me, the best way to handle this has been to face my pain altogether. This pain does not come from this event. It is my own ancient pain that has been triggered by my now ex. Staying with the pain, listening to it, feeling it in your body and letting it be there is a transformative act.
I recommend listening to Pema Chödron's videos or books. Maybe "When things fall apart". I personally have been helped a lot by doing the "tonglen" meditation.

I used to contribute to google maps. I had the same vision you do. But then I learned about their dark way of stealing people's data. All your contributions to google maps are now property of google. You are giving away your efforts so one of the richest world companies becomes richer. And keep abusing their users. So now I use openstreetmap.org
I used manjaro for 3 years or so and then been using EOS for similar time. Manjaro broke a lot of times. EOS is more stable for me.
