I am a beginner (three years in). When I had about two years of experience, I found a nice simple project in the Jan/Feb 2018 issue of Fine Woodworking. It is a shaker inspired step stool. The joinery is relatively simple and was a fun little project. I have put a link to the free portion of Fine Woodworking where they show a picture of it.
