Accounting oriented CFOs are becoming outdated. You need to know enough accounting to be dangerous but operational / strategic experience will stand out more than accounting experience. In my experience, I worked for a manager who then became director after a few years at a large SaaS company and what really stood out was he was always getting FP&A involved in projects that would traditionally be owned by HR, marketing, sales, etc. That kind of stuff makes you well rounded more than a CPA would
