Spring Cloud gateway is suitable here or not

I am building small application with multiple microservice.

1. DB based Authentication microservice using spring security
2. Microservice-2
3. Microservice-3 . . . might be more than 5

Should I use Spring Cloud gateway or external gateways like Apigee , Aws/Google Cloud Gateway, etc ?

What is standard approach to implement gateway in microservices using spring boot?
