3. --multi-pass-opt-distortion

I might be missing couple more things?
--no slow first pass, I think misses the point of 2 pass encoding. 2pass means to spend that much more time on encoding to get that much more quality or to hit that target size. Otherwise you would just stick to 1pass encoding for speed.

I would keep options 2 and 3, and add --no-strong-intra-smoothing --no-sao --multi-pass-opt-rps for some speedups as well.
