Thanks guys.
I obviously called it the wrong thing. Noobistic!
From what I understand "regular" HDMI has a max cable length of about 30', which means the second "room" has to be pretty close. There are baluns that work with fiberoptic cables that can send HDMI up to 500' and are HDCP compliant. I don't know which, if any, sellers are good, but here is a ramdom example of what I'm talking about

There are also HDCP compliant ways to lengthen HDMI transmission with cat 5e. Another random example:

As to the number of cat5e, or cat6, there has to be some number you would recommend. I'm thinking 4 at present. And of course with the very good pointer about the "extra pull", it might not matter if I'm off a few ... as long as I make all the mouse holes big enough. Also, not sure if fiber can be pulled in that manner, although maybe I could pull a little skinny conduit, if not put one there in the first place. Not sure if there is a little skinny conduit that doesn't crimp that a few fibers could be easily pulled through "someday".
So CL2, 12 ga for speakers it is.
Thanks again, both of you.
