Choosing good target/match schools can be a lot of fun as, if done right, it is a very personal process. What really excites you about a possible college experience? Small college with small classes and quickly working with the top professors in a department? Big college with big parties and sports and possibly grad classes? Competing for merit? Interdisciplinary opportunities? Robust study abroad? Robust support for internships? More academicky/nerdy? More pre-professional/work-hard/play-hard? Proximity to urban activities? Outdoor activities? Greek life, or no? And on and on.
A lot of kids your young age understandably do not really know for sure what they like or how to prioritize different things (indeed, I would not trust feeling that you do). So, people visit a sampling, get some ideas of what they like or don’t like, visit some more, refine again, and so on.
In the end, you should have a list of target/matches that are all exciting to you for specific reasons that coincide with your learned preferences.
But getting to there from here requires patiently working through a process of discovery, both about the colleges and about yourself.
