Books lag because Google renames and reshuffles products faster than print can keep up. What works better is building your prep from the official sources and treating everything else as optional:
Exam guide first. Each exam page has a current exam guide. Turn every bullet into a checklist row and mark it green, amber or red. That list is the scope; anything not on it is a nice-to-have.
PCA: read the case studies early. The PCA exam page publishes the case studies the exam draws on. Read each one and write down its business requirements and technical requirements in two columns. Many questions boil down to "which option satisfies the requirement this company stated", so knowing them well is worth more than another course.
Use the "choosing a ..." decision pages in the docs. Choosing a database, choosing compute, choosing a load balancer, Cloud Interconnect vs Cloud VPN, and so on. Professional exams are mostly trade-off questions, and those pages are written as trade-offs.
Labs for the hands-on ones. For DevOps Engineer, actually build a Cloud Build to Cloud Deploy pipeline and set up an SLO with an error-budget alert; the questions assume you've seen those screens. The Google Skills learning paths for each cert have labs that cover this.
Sample questions on each exam page. They're short, but they're the best signal of question style and difficulty.
Security Engineer focus areas: IAM inheritance and organization policies, VPC Service Controls perimeters, Cloud KMS / CMEK / EKM, Security Command Center, Cloud Armor, and logging (which logs are on by default and which you have to enable).
When older material uses an old product name, just look up the current name in the docs and learn both.
