That's tons of different techniques! Personally I also practice a variety of techniques but perhaps the most important ones for me should be those which define my most important weaknesses (wide vibratos) that's what I should work on. I used to exclusively use a longitudinal vibrato (finger swaying along the length of the string for a very fast but shallow vibrato) but now I work more on the so called "butterfly vibrato" which is more like a fast bend/unbend - more commonly used. Both have their uses I find. I'd like to be able to do a clapton style variety too where the whole arm moves the string from side to side - this can be combined with the shallower longitudinal vibrato too giving a sort of crying purring ululation.
