How do you decide which customer feedback actually becomes a roadmap item?

Every team I talk to has more feature requests than they can act on, and most of it doesn't come with clean data attached, just a support ticket or a Slack message from a customer. For those running product teams here, what's your actual process for turning scattered feedback into a prioritized roadmap? Curious whether people are doing this manually in spreadsheets, using a dedicated PM tool, or something else entirely.
