This is a good update to hear. I was sure you were due to need a knee manipulation under anesthesia, I'm glad to hear you are doing better.
I personally wouldn't change any fit items on my bike over the hamstring soreness yet. Try a few more rides, ease up to longer distance, stretch. Start slow. It's been a while with some major physiological changes. Give it time for your body to start fitting your bike again.
FWIW, my two racier bikes have been in storage for two years. I'll be reunited with them this fall. I'm scared how they'll "fit" after two years of gravel and mountain biking.
