Places to find Internships for Rising Juniors in Highschool

Does anyone know of any good internship opportunities for computer science or engineering? I’m not sure what to do this summer and I’m applying to only 3 camps as my options are quite limited since I have a summer birthday. Do summer camp’s really matter? What can I do to enrich my experience this summer?

UCSC SIP, stemAway are the only good options I have. Which ones are you applying to?
