It’s very frustrating. My left lower lobectomy was May 2023 and I still have SOB when bending over. My situation was complicated because I am on a steroid for a different condition and I have gained 20 pounds. My long course ends tomorrow so I’m hopeful I can shed the weight. But that wont rid me of SOB I’m afraid.

I too live in Florida. My lul lobectomy was in February.
I tried to stay inside in the heat and humidity. Have you considered trying pulmonary rehab? You need a referral but it really helps. And no Dr should have said 99% recovery. If you work at it you should be able ylto get about 90% of what you could do before. I don't think that's too bad.

What do your pulmonary function tests say? And heart tests? I had shortness of breath before my VAT wedge resections. I have three reasons for my shortness of breath: interstitial pulmonary fibrosis, radiation pneumonitis and pulmonary hypertension and of course I have reduced lung function. It takes a specialist with specific expertise who will cross reference your tests to diagnose potential causes. Also have you caught anything like Covid?
You mentioned hot humid summers in Florida, I know how they are. If you were not exercising after your sugery (walking, and walking) you may also be deconditioned. They got after me for that!

I am 9 months out from an URL lobectomy. Humidity definitely affects my breathing. I live in a dryer climate and when I go to the coast I feel the difference. Abuterol inhaler helps but doesn't cure it. I avoid going out into hot high humidity.
