One thing that many guides tend to skip is how to install software. People coming from Windows might try to install software the “Windows way” by going to the website and downloading them. That is just likely to cause pain and suffering for a number of reasons.
Instead, every beginner friendly distro has its own flavour of software centre that users should be encouraged to use instead. Maybe even include a link to flathub in the guide or something.

I don’t know if they still do it, but Mint used to do staggered updates (through their update manager) for some packages. They would start out making the update only available for, say, 10% of people and then slowly built up to 100% if no issues were discovered.
