I have 5 separate Numbers documents open right now. mostly because I'm lazy about closing them. Maybe I should be more disciplined... either way, that renders this statement incorrect, and likely renders the rest of the post moot...

What 'workaround' are you talking about. As I mentioned, File -> Open has always worked for me. Not sure why invoking the terminal would be any different/better.

Without knowing what 'workaround' you were using, or how it's changed, it's impossible to confirm or deny this one, other than the fact that Numbers has always (that I can recall) been able to open multiple documents, and therefore this is likely moot anyway.

that likely depends on the setup of your shortcut...

Numbers is a GUI app that doesn't have any command-line options. There are some standard command line commands such as 'open', which can use Numbers.app as a parameter/argument, but it's not related to Numbers directly.
To use 'open' to launch an application:
open -a <appname>
e.g.:
open -a Numbers
To open a document in the default application:
open /path/to/document
e.g.
open ~/Desktop/my.xlsx
to open a document in a specific application, combine the -a switch with the document in question:
open -a Numbers ~/Desktop/my.xlsx
But this is still no different from opening the document using File -> Open.
The only thing that comes to mind when you say you can only open one document at a time is if you're running in full-screen mode, where the document takes up the whole screen, meaning you can't see other documents. If that's the case, move the mouse to the top-left corner of the window until the close/minimize/zoom buttons appear and click the green button. Does that reveal the other open documents?
