I'd just use the Toyota stuff. Coolant is good for ~100k miles. I don't think there's a huge advantage (if any) to alternative coolants - they're not going to be significantly cheaper, even if they last longer you should still probably change them every 100k (and it's not that expensive to do so anyway), and you run the risk of some incompatible formula causing issues with gaskets and seals (like we've seen with some cam tower leaks, though admittedly that was Toyota using the wrong sealant)

Anything that goes on or in a Toyota JDM engine should be OEM

Drain and fill, it is too difficult to get every drop out so you’ll end up with diluted coolant if you flush.

I’d get 3 to cover your bases, especially if you manage to find both block drains. The driver side is more hidden.
