Advisor thinks I’m ready to graduate, committee still needs convincing — advice?

I’m a STEM PhD student with an upcoming "checkpoint" meeting. My advisor believes that once I finish my current projects, I’ll have committed to enough work to graduate. There’s a clear path to completion, and we’re intentionally avoiding too many abstract future directions at this point.

However, my full committee still needs to agree. On my advisor’s advice, I’m planning to be relatively quiet about potential future directions, but I still need to convince them that I have enough solid material for a complete dissertation (i.e., enough chapters).

I don’t plan to stay in academia, and graduating is my top priority—especially given current funding constraints. There’s a chance that funding issues may make the committee more open to approving graduation, but I don’t want to rely on that alone.

Does anyone have advice on how to approach this meeting or how to frame things to convince a committee that you’re ready to graduate? What arguments or framing worked for you?

TL;DR: Advisor thinks I’m on track to graduate after finishing current work; committee still needs convincing. Looking for advice on how to frame progress and scope to avoid “one more experiment” requests.
