Create private NAT gateways in the same private subnets as the EC2 instances.
Create public NAT gateways in public subnets in the same VPCs as the EC2 instances.

Explanations:
NAT gateways must be deployed in public subnets to allow outbound internet access; they cannot exist in private subnets.
Private NAT gateways are not a valid AWS concept; NAT gateways must be public to route traffic to the internet.
Creating public NAT gateways in public subnets allows EC2 instances in private subnets to access the internet while keeping them secure.
Private NAT gateways are not valid in AWS; NAT gateways must be in public subnets to function properly for internet connectivity.
It seems to me that the answer is:
Create public NAT gateways in public subnets in the same VPCs as the EC2 instances.
