Was about to write the same - those options do exist already. It works quite well in my experience. Although quality may depend on how well a specific city mapped out. Melbourne for example have options for accessibility (City consuls pays for mapping accessibility scores\options and I guess those details help to plan in maps and just generally a good city benchmark). Preferred and connecting modes works well too - one can specify if ride service or drive is not an option or bus is meh. One thing I wish to have there is 2-3 presets of these options so I can quickly switch between combinations of - "get there fast", "get on specific time", "get with my most comfortable preferences". It's all there, just switching it every time is a bit of annoying.
