Is Anyone Else Overthinking the CTA in Cold Emails?

One cold email pain point I keep running into is the CTA.

I can spend 15 minutes writing the email, then another 30 minutes debating whether to end with "Worth a conversation?", "Open to learning more?", or "Can I send over a few ideas?"

Sometimes the softer CTA gets replies. Other times a direct question works better. And occasionally it feels like the CTA makes no difference at all compared to targeting and timing.

Curious if others have found a consistent approach, or if the "perfect CTA" is mostly a myth.
