The first role of a school is to keep children safe. The second is to provide a quality education. After that, a school can be whatever it chooses. It can have a religious focus, it can have an academic focus, a sporting focus, a performing arts focus, anything! That focus will have a strong impact on the culture of the school. Culture is important.
You really need to visit a school, read its literature and talk to community members to get a feel for the culture. Have a look at their social media and newsletters too. They will give you a strong indication of what is deemed important in the community.
Make sure the values and culture of a school align with your own. There is no point choosing a school and then spending years railing against its very essence. It simply doesn’t make sense. Find your people.
