From that list, I picked wireless charging. I am honestly more happy with my 6s plus than I have ever been with an iPhone, but that wireless charging would be icing on the cake. I realize the argument against this is that we still need cables, etc. but I generally set my phones down on my work desk which already has an Qi pad and it would be second nature to just set it and forget it (Ronco should make these). I don't always plug my iPhone in because I am not constantly at my desk. But sucking up an extra couple percent of battery here and there would be nice, not crucial, but nice. I can also see this tech being great for a car mount. Drop your pohone in the mount, no cables needed, music, gps, phone all play through bluetooth and my phone is charging. This would reduce the wear and tear on cables. RIght now, cables last me a year, max, in my car, which isn't bad, but hey, no cables is "green", right?
