How should I cut my hair? No

My hair is fine and straight in the front, and curly in the back with straight hair that lays over the curls. Even when I straighten the under curls, they shrink up, which emphasizes the stringy straight front pieces. I was all set to chop it all up and layer the straight pieces in the back to allow the wavy section to show, but I watched a video with Rami Jabali, and he said if your hair is limp you should save some length so all of the focus isn’t on the front. So now I’m torn between a short layered bob, possibly an undercut bob to get rid of some of the curls, or growing it out and trying to round the front as Rami said. The picture of me with short hair was 8 years ago and my hair is much flatter now. The last picture was my proposed cut until I saw his video.
