Let's say just like for example like MacOS. It's awesome we have so many tools but at the same time lack of some kind of standardization can seem like nothing works and you get overwhelmed. I'm asking for people that want to support Linux or not so tech-savy people.
Kinda don't think you can its one of the beauties of Linux, there's so many different flavors of it. Best thing that would've helped me as a beginner would've been like a collection of all the wiki's and basic knowledge in a single space instead of searching through different sites for a problem or terminal commands, which I bet exists but I just never looked too hard. Also documentation of common problems would've been big for me (especially for older devices) like drivers no longer being supported by kernels and solutions like using the open source version instead.
