Coupon books are used in France. One coupon for each candidate. Voters privately choose a coupon from the book at the poll site and put it in an envelope. They're distributed and counted by volunteers very quickly and there are checks for integrity. A final count is ready for the evening news. There is a full paper trail. Very hack-resistant!
I volunteered a bunch of time. Nice to see, nice to do. Simple, stupid, and so far good enough.
In America, it’s common to be able to vote on 20+ items in a presidential election. Plus, each state is responsible for conducting its own elections.
So we would have 20+ tickets and you'd put them in your respective bin for whatever elected position or proposal. Then each bin can be counted later, smaller locations could just have the volunteers count each bin sequentially, larger locations could have each bin be counted by it's own group.
