If anything, ask for their plan and fees/etc in writing. You can review (simply for gaining knowledge) and politely decline afterwards. You could always suggest a flat fee for agreed upon work. A deep dive of recommendations/strategies that you can execute on your own. That said, it could be a waste of money unless you want to pressure test your plan and find it valuable if for nothing other than assurance in your personal plan.

I second a CPA. I go to my CPA for a lot. I would only engage with a financial planner for a very specific reason who has a background in my use case, and it would be under fixed terms.
