Though there's lots of different ways to use AWS, so the experience your team brings may be a sort of complicated venn diagram. Even within a simple product, like deploying serverless, there's SAM vs serverless framework, vs scripted AWS cli. Using stacks or not. Using another layer on top or not like Terraform or CDK, and so on. Then the actual pattern of using it, Lambda layers, heavy or light patterns for securing things, using versions/aliases or not, and so on.

It wouldn't be unusual for a tech lead to pick some approach that ends up being new for the rest of the team. So some ecosystem with fewer choices would probably be faster.
