We picked up some touchless hand soap dispensers. We got the simplehuman brand which I think was one of the one recommended by America's Test Kitchen.

Then we bought some more to give to everyone for christmas because we liked ours so much.

Lot of other good answers in this thread: split keyboard, trackball, iron skillet, etc. These items also spark joy for me. And I should probably stop thinking about getting a bidet and actually get one.
