3” vs 5” what would you recommend and why?

Currently flying tiny whoops but plan on building something bigger over the winter for no other reason than why not. I’m more of a flowly freestyle type and I’d like to be able to carry a go pro.

What would yall recommend? What frame? What size? 2s? 3s? 4s? 6s? And so on. Hell maybe even a 7”. I’m open to suggestions.
