The URL you referenced might not be a roadmap, but it certainly is a good jumping off point to find a suitable project. There are lots to choose from.
Perhaps you could start with the distro you are already using, look at what annoys you and you have skills to approach a solution. Look at the issues list for that project, pick one, do whatever is required, submit, repeat.
Assuming you don't plan on kernel hacking, Some areas with many issues are WiFi, Wayland, audio, battery / power management, etc.
