You can also take two boundary curves (with the same number of points), sort the order of the vertices and the point numbers so that they go in the same direction, and make a blendshape between them with a coefficient of 0.5. This is if you don't want to deal with VEX

Thank you very much for your response. I will give it a try. I really appreciate it.

Given a starting edge, if you know the geometry will follow exactly that topology it's somewhat straightforward to walk along each pair of edges and find the center point.

Thank you so much!!!!!!!!!

Ah ok, I see.
Ok, that is not a trivial problem. Are the planes modeled with an edge connecting the corner points?
If so you could use a polysplit sop. If not I don't think there is a clear solution other than the straight skeleton node.
Can't the planes be created with a center line in the first place?
Could you share an example of these planes?

btw: why did you start a second thread on this issue? please, keep it to one and delete the other.

This 2D plane was directly created by me using the Labs Regions From Image node to recognize specific colors in the image, rather than by drawing straight lines. Ideally, when the image changes, the same colors would be recognized, and the centerline would be calculated accordingly. So it's indeed a bit tricky.
