Great to see you have a new lens and like all new lenses the more you use it the more you will understand its capabilities.
Certainly for project 2 it will be an excellent choice of lens. You could use it on project 3 if your DSLR camera is not a "full frame" camera, however don't get weighed down with technical stuff in the early projects. If you are unsure if your camera is a "full frame" camera or not, then if you have a 50mm lens that would be a good choice.
Let me know if you need anymore advice, good luck.
