aws_vpc

This module can create:
VPC, Internet Gateway, Private Subnets, Public Subnets, Route Tables, NAT Gateway, VPC Endpoint for S3

If you create 2xPrivate Subnets and 2xPublic Subnets with IGW and NAT enabled, Subnet will have names:

xyz-private-1
xyz-private-2
xyz-public-1
xyz-public-2

If you create 2xPrivate Subnets and 2xPublic Subnets with IGW and NAT disabled, Subnet will have names:

xyz-private-1
xyz-private-2
xyz-private-3
xyz-private-4

Where xyz is VPC name.
