They all are.  The selection depends on user preferences and habits.

You can learn about it from the Emacs manual, of course.

They don't need to consider all of them.  They can take them one at a
time.  The documentation should tell them enough to make the decision,
perhaps after some experimenting.  Then they can go to the next

IOW, the collection is just a device to enhance discoverability, in
presenting the options some class of users are likely to benefit from.

That's the purpose of presenting a relatively small group of options,
out of many hundreds we have.

I write Lisp.  But I'm not a user of the kind we are talking about, so
what I do have little relevance here.

We already have that: each mode file includes options for that mode.
What will we gain by having another file with those same options?
