Something like this:
https://www.homedepot.com/p/23-32-in...5189/100003769. T&G is very good for a floating floor since it keeps the edges flush, which is important when you don't have any joists to screw the edges into.
I would avoid OSB since it doesn't handle getting wet as well as plywood does (neither is waterproof but plywood goes back to normal after it dries out, while OSB is permanently damaged even after it dries out). It's a lot cheaper per sheet but you only end up saving like a $150 or so for a whole floor, which is a drop in the bus bucket IMO.
I would also avoid cheap plywood from Craigslist from a guy who acquires crates used to transport juice concentrate from South America and disassembles them. If you think that's oddly specific advice, you're right.
