KDE had exactly that back in its 3.x era, actually. It had a first run wizard that allowed you to choose things like whether you open things with a single or a double click, and options were largely organised based on platforms with similar conventions (as in, it had options like "single click selects, double click opens (Windows style)"). It was remarkably friction-free actually, people could just pick the mode that they were already familiar with and that was that. It had all the good parts of "the right default" (i.e. the "right" default was always the one you liked best) and required exactly one click to configure.
