Walmart sells a 5-gallon jug of Castrol Transmax CVT (Nissan NS-1, NS-2, NS-3 compliant) for $23-$27. I've been using it in my 2021 since around 67,000 miles, and I'm now at more than double that mileage without anything serious going wrong. There is a slight whine from time to time that started around 115,000 miles, and it's usually 50/50 it will happen on a cold start, and usually goes away after the car is up to operating temperature. I believe other owners have mentioned the whine and were using Nissan brand, so my take away is that fluid brand doesn't make a difference. Whatever's going to happen to the CVT will probably happen due to driving habits, poor maintenance, accidents or normal wear after higher mileage, etc.
