I don't think these systems are specific to the front or rear wheels.
However, there are definitely differences between SCBS and Advanced SCBS. Not sure about the differences between the years, but you can just look up to see which trim and year combination has which system available.
For 2019, it looks like SCBS is standard on the Sport trim. While the Touring trim and up get Advanced SCBS.
SCBS is just a low speed (19mph and under?) automatic braking system that uses lasers at the top of the windshield to detect potential crashes.
Advanced SCBS utilizes a radar sensor in the grill and a camera at the top of the windshield to provide automatic braking at higher speeds. Because of the additional sensors, it also meant that you get adaptive cruise control, pedestrian detection and lane departure detection and lane keep assist.
