you are forcing output fps (-ofps) without any video filter that
affects framerate. That's probably your problem. Either leave out the
-ofps, or add an inverse telecine filter (I'd suggest to inverse
telecine).

your options are already the best settings. You can't expect much more
gain from using more aggressive options.
Either raise bitrate, or scale down the video picture size (-vf scale).
