Although you will still definitely have assignments and readings (not sure what college wouldn’t) I think it is worth looking into Washington College in Maryland. Their motto is “Do it all, do it here” So many students double major because they end up loving the different classes, but you certainly don’t have to if you want a slower pace of classes. Students start their own clubs and Student Interest Groups often. Very supportive community, collaborative. Professors really shine and are part of the community. My child wanted to do something very different than the school currently had, worked with professors, got a grant, and is not opening up something new at the school that has to do with her major. So a lot of openness to new ideas and professors who will help you create them (help with grants, etc). There is a museum on campus for the students to showcase their art, there are orchestras and bands and different types of dance clubs to join, and a Makers Union. The anthro major is strong (all of the sciences, writing, psychology, pre-law/pre-med are very strong, with business up and coming. The biology class goes out on the river or into the field often, and the student body is very diverse in terms of style of dress, music they like, hobbies, socio-economic status as well as ethnic background. They have a day trippers club that has gone to NYC, Annapolis, Philly, and DC. I am not sure about their transfer experience, you may need to join clubs (there are many and easy to join) to meet people as a transfer.
Also, as others have said, it may be worth taking a year to go to Community College to take several classes in different majors to find out what you love!
