If you don't need 4k, Canon 80D would be a much better choice for video.

80D has dual pixel autofocus which is actually better than a6500.

That I dont know. You have to do further study. I only read about it and that most video guys prefer 80d over a6500 cause it has more usable features for them than a6500. Vari-angle screen, touchscreen, dual pixel af with almost no focus hunting, plus it has headphone jack that a6500 doesnt. Canon 80D to me seems like a all purpose good video cam for vlogging and general video making.

a6500 is no slouch either but heard some issue like screen dimming when recording 4k, no headphone jack and such. The touchscreen also less responsive than 80D. Also, unless you have capable computer, handling 4k video and its storage can be a chore.

Either way, there's no mistake in choosing either. Except since you mention you already have canon lenses, 80D is probably preferable. There are adapters to adapt canon lens on a6500 but it is either expensive or the af is too reliable unless you dont mind manual focus.

On 5dmkiii, it's actually also good except lacking touchscreen and vari angle screen means little bit more work to do video.

Thats a misconception. For switching focus between foreground and background, 'advanced' will most likely use manual (but really depends on your problem with af system). But for tracking moving subject in frame, reliable autofocus is important. Its also applicable when you doing travel video when you may not want to fiddle with manual lens much.

Take GH5 for example. You can still hear a lot of complaint from video shooters that its af system sucks bad even from pros especially the af tracking meaning even advanced also relies of af capability.
