I think the best way to find a project is to scratch your own itch. What kinds of problems do you face that an existing tool could solve, if it just had that one feature? That is how I ended up contributing to maintaining Seleniarm for RaspberryPi and ARM machines.
Also, don't worry about asking questions. Most maintainers are more than happy to help new contributors. Many projects need all the help they can get.
