Hey - welcome to AZ.
A couple of nice spots that you might not think about:
- Lost Dutchman State park - nice shots of the superstitions at sunset. That is a close place you can get to right outside of town.
- Watson lake near Prescott can be great on calm days, at sunset or sunrise.
- If you go to Sedona and can hike, go about 1.5 miles up the West Fork of Oak Creek and there might still be some fall color. It is a little late, but maybe.
If you go to Sedona but are not able to hike - you could try Red River Crossing - if you do not mind copying everyone else for the iconic shot of Cathedral Rock!
My color is off on this one- need to fix it...
- for shots in town, try Sunrise or Sunset at Tempe Town lake,
or Botanical Gardens.
A few ideas.
