You are correct that the Florentine street pronunciation varies somewhat when it comes to hard sounds, however I would think it more correct to say that the emphasis simply moves further back in the mouth, from the front of the mouth Italian pronunciation to a more guttural back of the mouth pronunciation. The "CH" however never becomes a soft C like CH in English.

Lastly, Veneto (I speak it daily with my 98-year-old Venetian mother-in-law) is not a different pronunciation but rather different words. Nobody from the Veneto will pronounce a written word differently than somebody speaking standard Italian. They will however readily transliterate into Veneto.
