Is this procedure likely to improve my breathing capabilities? (Photos)

I have had a very difficult time with cardio based activities for years now. When doing cardio, I resort to mouth breathing as it is extremely rare I can breathe through my nose when I’m exercising. I always feel like one of my nostrils is completely obstructed. I have a hard time getting quality sleep. I can be asleep for 7,8 or 10 hours and I will still wake up feeling as if I barely rested. I saw an ENT last weekend and after receiving the CT scan they said I have a slightly deviated septum, enlarged turbinates and an air pocket in one of my turbinates. They recommended a Septoplasty + Turbinate Reduction. My question is, how likely is this to improve my breathing during cardio based activities? How likely is it to help the other symptoms I described? If it is not highly likely, I’d rather not do the procedure. Thank you in advance.
