Unpaid Consulting Internship

I am a sophomore and just got two offers for management consulting internships at smaller firms for this upcoming summer. My dilemma is that neither of them are paid, and I have a final round interview for a paid internship at a large FinTech company tomorrow. I am no longer interested in finance, so taking that opportunity, although paid, would sacrifice valuable experience in consulting that I could leverage for my junior summer. Which should I take? And if I decide to go with the consulting experience, what should I consider when deciding between both firms since both are unpaid?
