Agree here - learn a declarative infra description language like terraform, or cdk, or pulumi, or something. Infra-as-code will put you on the right side of things for cloud infra.

I say that as a person who is not super bullish on big cloud architectures. So, also learn a more 'imperative' tool like ansible (even with its sucky syntax), for repeatably provisioning hosts.

Orgs that don't use tools like that are, in my opinion, strictly of a lower level of maturity and having-shit-together-ness than ones that do.
