I am encouraged by the fact that you realize what school your child attends is your is choice
As an educator who has taught in private, and public school I love that fact that a parent realizes that they can choose which school is the best fit for their child. Some children will shine more in larger schools while others will be more comfortable in a smaller school. Check out your community and see what options are available to you. Our older two kids went to a neighboring town's school with much larger class sizes and activities. The younger two have enjoyed the smaller intimate setting of our rural school after starting out at the Catholic school. Consider your child's personality and strengths. Visit the schools and see what the overall personality of the school is. Sitting in classrooms at different grade levels will let you make the best comparison. Best wishes with exploring your choices. Remember your decession is not a lifelong commitment you can always make an new if the school is not working for you.
