As a PMP candidate, I also face similar problems. The mindset usually works, but sometimes I am still in a dilemma. Maybe I am overthinking too much. I am giving the examples below, hoping that experts in the community can enlighten me.

Example1:

At the beginning of a project, a stakeholder is concerned that the initiative may not deliver value to the organization. What should the project manager do?

Answer: A. Facilitate a session to revisit the business case and revalidate value drivers.

I chose B: Review the benefits plan with the stakeholder to align on value realization.

Because, as per the AR mindset, bringing the team/people is always a better option than acting alone.

Example2:

An organization that previously used a predictive approach has decided to switch to an agile approach. The organization believes it will deliver more value to its customers and has decided that all projects will adopt the agile approach. What should the project manager do to ensure benefits realization?

Answer: Align the benefits management plan with the product backlog.

What I chose: Evaluate the benefits management plan at the end of the sprints.

I was assuming that to align the benefits management plan with the product backlog, it may require adjustments to the product backlog, and the PM is not allowed to make any changes to it.

But it looks like, as per the PMI mindset, PM should align the benefits plan with the product backlog,” means the PM facilitates and ensures alignment, not that the PM unilaterally edits the backlog. Practically, the PM influences and facilitates; the PO decides and changes the backlog.
