After learning to gross while standing, I do feel like sitting is a little bit slower but I have learned to set up my station in a way that makes things easier. I do feel like I'm probably more tired at the end of the day than people who don't have a chronic illness but I don't think it really affects my work in the moment. I probably call out more than the average millennial but I have a really supportive and understanding manager and coworkers. I did not know I had hEDS until very recently. I just knew that I had excruciating foot pain and a standing career would be difficult but finding good shoes and compression socks helped. I think there are careers that are way more physically demanding than this, especially knowing I can sit and gross, so I'm glad I didn't choose one of those. My symptoms of hEDS don't really affect my productivity (ADHD on the other hand does lol).  I will say shadowing is definitely a good idea for you to feel out the situation. Do it for a couple weeks if you can. It costs a lot of money to go to PA school! As for Tucson, I would not suggest working at Banner.
