Having no interest in video, I'd choose the 7DII. I'm also told by others (I haven't shot video on my 7DII in over fifteen months of owning it) that video on the 7DII is pretty good. It doesn't have a touchscreen, but videographers managed for many years without one, and I'm told (again, no personal experience) that selecting the focus point with the joystick is pretty easy. No 4K, of course, but I have a hard time seeing why 4K is necessary for home video. It seems like a waste of space and processing power to me, but I don't even own a 4K TV, and see no need to get one. As for still shooting, the 7DII is simply amazing. The AF system is top notch, and it shoots at 10fps. It has 65 selectable AF points, all cross-type. The D500 has 55 points, only 35 of which are cross-type (the other "points" are marketing speak--Canon has those too, just doesn't count them). For all I know, the D500 AF system will be as good as, or even a bit better than, the 7DII. No-one knows yet. The sensor may be slightly better too in the D500. It might even be better enough that you can tell the difference, if you look at your image at 100% on a screen from one or two feet away. For regular, and sane, display sizes and viewing distances, no-one will be able to tell the difference. If I had no investment in either system, I might be tempted to wait until the 80D and D500 were available, and then choose between the 80D, 7DII, D500, and D7200. Given that I've used Canon for many years and have a lot of lenses, I think it would be sheer insanity to switch systems in the hope (probably vain) of vanishingly small perceptible differences in results.
