There are some HDMI standards to be aware of. HDMI versions have added features like ethernet and support for 3D and 4K television signals.
HDMI is a digital signal so going for a thick gauge is not important here.
For those running long lengths or need thin cables, look into REDMERE technology of HDMI. Monoprice has them. They can only be run in one direction but the cable is very thin and flexible. I had the Amazon basics HDMI cable once. Braided and beautiful, I had to get rid of it as it was so thick that it broke a HDMI connector in my receiver. The REDMERE cables will never have that problem. They are worth the cost from Monoprice IMHO.
