So far 192kbps is not standard
The most standard is still 128kbps, 192kbps more towards optimum bitrate for CBR

For me, I prefer VBR all the way, and also like OGG audios, sound quality good at low bitrates, followup by AAC

As for FLAC and Monkey Audio, I have some of them, although file size is big, just accept it anyway because it is Lossless and smaller than WAVE files
