I came across this post which helped a bit: https://buddypress.org/support/topic/conditional-bp_register_group_extension-how/

I updated my gist above to reflect that, and I now have new pages added ONLY to the specific group ID I specified. Awesome!

Holy crap, you are a gem. This worked perfectly! I had tried changing the archive and single names before, but nothing was changing. Adding the custom menu item and linking to the new archive name did the trick.

Thanks so much!
