Site URL organization
I looked for help in the forums and handbook and didn't find the answer, probably because I'm not quite sure exactly how to ask the question. In my examples below, A, B, a, b, etc. are all just examples...I would use more descriptive names in the real site.
I want to make a site as such. There are five first level pages: (A,B,C,D,E) and each has multiple second level pages (a,b,c,...). These second level pages can have lower level pages as well. So all of the following pages have content:
/A
/A/a
/A/b
/A/b/z
/B/a
and so on.
The sites I typically make only have first level pages (/A, /B, /C, etc). How do I make pages whose URLs are below this first level? I know I could use the Path module and content creators could enter the multi-level URL, but is there a better way to do this? Is there logical and simple method to use so that the page creator doesn't have to know the whole path, just the last part of it? Or is the Path module the most logical and simple way to do it?
If I don't make sense, sorry. I did the best I could.

Use the pathauto module
I believe it has the capability to do that.

If I'm not wrong, you
If I'm not wrong, you probably come from a wordpress background and you're looking for the wordpress URLs that can be manufactured with the page-parent settings.
No, I can't think of a way in which pathauto will actually achieve that..Unless you actually manage to reduce all existing pages as [parameters] for the default path assignment for pages and an appropriate system to select 'page parent' like in wordpress.
The best work-around IMO would be to share a common taxonomy parent amongst all the pages you intend to sort into the hierarchy.. pathauto can probably pop in then.. That should be something that can get as close to as effective as you need it.
