I feel like any job that allows you plenty of sitting time, whether it’s on the computer, organising, or documenting. Things like that were you can spend time sitting not necessarily the whole shift if that’s something you can handle. Honestly if a job isn’t willing to accommodate you because they assume you’re somehow less capable due to that then you don’t want to work there anyway.

Maybe some kind of data entry job would be good for you, since all you would be doing is sitting at a desk and typing. Anything online/at home could be good for you too!
