Regarding ID camps - at this age it is likely mass invites but attending cheap, local camps on local campuses can help. We did a rural d3, more academic d3, and a larger d1 early on just to get my daughter in campuses and starting to think about what she wanted in a college experience. Going to low key camps early also takes some of the nerves away later.
I would avoid the larger, expensive, multi school camps.
After freshman year we only attended camps at schools where the coach had either personally reached out, contacted her club coach about her, had seen her play, or she had detailed and personalized text and /phone conversations with.
Make sure to be emailing coaches and sending film, resume, and game schedules. We found playing in national showcases much more valuable then camps early on
