16-35, 50, 70-200 is pretty much what I want for a 3 lens set up
But I put Zeiss 21 instead of the 16-35, as IMO 16-35 can't justify the value of 1500ish brand new and 1200ish used..
But I lose LOTs of versatility since I did this.
If you don't care too much on F2.8, you can get the 17-40 or even try the new 24-70 f4 IS
I'm still struggling too, I'm actually selling the Zeiss, which is fantastic but not suits me well
