I would suggest a job where you are doing mostly following directions and things are set in a routine. I used to volunteer at the library in high school. I loved it, not only because I found good books. I would check books in and out, and put them back on the shelves. I also helped in the school cafeteria. I would be selling the pastries and snacks. Even though it was busy and there were a lot of people, there was really little interaction. I mean, someone would tell me they wanted some cinnamon rolls, I would give them to them, and they gave me a dollar, and I gave them change. The most complicated thing was when they asked me how much a bag of chips or brownies or whatever cost. That was as complicated as it got. They both needed little training, like a few minutes to show me how to check in a book and such.
