Not sure if you've already ordered your speaker wire yet. I can recommend, based on test specs and research, belden 1311A cable. I just ordered a 500ft case for myself and can report when I get it.
As far as I have found it is the best bulk speaker cable available on the market. Comes in 500ft or 1000ft spools. Companies like blue jeans cable sell it at around 1$ a foot for similar products. I dont know for complete certainty, but I'd guess expensive cables are often dressed up and rebranded belden.
A 500ft spool would get your room close to pulled and cost roughly 350$. I deal with belden stuff all the time at work and can stomach the cost for getting something proven in commercial use. Good luck with whatever you choose.
