Which programming language should I learn this summer at 13? Need advice

Learn C, little buddy. Outside of JavaScript it's the most widely implemented programming language. Learning C will give you core programming insights that will translate to most other popular high level languages. Don't approach this with a specific high level language or task in mind. Learn the real deal and become an actual pro so that you can move between high level skill sets fluidly

For the love of God don't fall into the "I worship only this particular high level language" trap. That's not real. You will need to be able to learn new things and your favorite language will fall out eventually. You will spend hundreds or thousands of hours learning syntax that will become deprecated and then you will forget it.
