There is no difference. It's only a matter of what you want the fallback 
to look like in older browsers.

Nested menus means submenus.

There's no difference except <command> doesn't show in old browsers. 
(Which might be good or might be bad depending on what you want.)

Well you'd use a context menu when you want a context menu, and a toolbar 
when you want a toolbar... those seem pretty clear. :-)

The "list" feature is just for backwards-compatibility, it's not really 
needed.

Not sure what you mean.

Theoretically, the styling here is expected to be done via CSS 
pseudo-elements.

Adding items to context menus seems like a pretty well-understood 
convention; could you elaborate on why this example is confusing?

You can use form controls (no <command> at all) when you want fallback.

Not sure what you mean.

The goal for toolbars is for them to be in-page.

Indeed.
