Went in Nov and did like you did, FP for both Electrical Parade and the fireworks.
Absolutely no regrets for the Electrical Parade FP. It is right in front of the castle and makes for an amazing parade viewing/picture spot. We sat right on the curb, and everything looked 10x better passing by during the parade with the castle towering feet from it. For my family at least, I would take this FP above any other at MK since I wouldn't wait an hour+ to get the spot normally, but if I tried I could get any ride with minimum wait depending on the time of day I go.
The Wishes FP is kind of a hit or miss I guess. It is off center so for a small few of the fireworks we didn't have the best angle, but overall it is a great spot since you are so close to the castle. Again I would probably still take this as I wouldn't waste time at MK sitting to grab parade/firework spot.
