api versioning strategy which approach works best

hey everyone, im looking to get some insights on API versioning. we're building a new set of microservices and want to avoid breaking changes for existing clients down the line. what's your go-to strategy? are you big on URI versioning (e.g., /v1/users), header versioning (e.g., Accept: application/vnd.myapp.v1+json), or something else entirely? what are the pros and cons you've seen in practice?
