What is the best approach to influencing C-suite executives in a business strategy decision?

I've definitely been in this exact situation where my key stakeholders were the C-suite (my boss was the CMO for starters!) I don't think much has to change to what you've said, as PMM's we continue to be the guardians of the message and ensuring things like product:market fit are optimal and our value propositions to our customers are clear and differentiated. Ensuring thats well understood across different departments doesn't change. A good example is working with sales leaders (including Heads of Sales and CRO's etc) to influence the impact of enablement. Seeing that productivity and sales output is such a key metric for these leaders, product marketing leaders can showcase why there needs to be more accountability with solution/product training to ensure customer AND sales success. This is meaningful to them (even if its just a means to an end..i.e revenue!) so they will get behind it and partner with you to ensure their organisations are participating. This is just one example but it represents similar initiatives with other leaders where sharing objectives helps create clarity around the contribution value of functions such as product marketing.

To influence C-suite executives in a business strategy decision, focus on aligning your goals with theirs. Understand their priorities and show how your ideas support company objectives. Use clear, data-driven insights to back up your points and keep your communication concise and focused on high-level outcomes. Build relationships by being proactive and transparent. When you're a VP, conversations with the C-suite can be deep and challenging because you're discussing strategic, big-picture ideas. It’s crucial to present your insights confidently and demonstrate how they directly impact the company’s success. Be prepared to engage in tough discussions and provide solid solutions.
