There"s a lot of personal preference and how you use the bike involved into what is your best size. As an example, based on my experience with my Canyon Stoic in size M, I would consider this frame in size M as well and I'm 1,80. Main thinking is that I'd prefer a more nimble bike with a shorter wheelbase. If the frame is too small, you can always raise the seat post or put on a longer stem.

760mm for handlebar is a nice starting point, you can easily cut off a few cm if needed. If you're not yet used to such a wide handlebar, it may get some time getting used to.

Measurements on my own legs, both inseam and lower leg bone, indicate to 170mm crank length, but I could do with 165 as well. The 170 on my Canyon don't cause me issues. There's a trend towards shorter cranks as it increases comfort and with that power output. Your mileage may vary.
