I know I have found the fix for this before, But for the life of me I cant find it again. what causes the light along the edges like this?

Put a nodraw brush behind the displacement there. The edge of a displacement might still be looking through the displacement connected to it. And when there is a skybox texture it will just accept the light it emits. The nodraw behind it will fix it

Or a blocklight texture. Works just as well.

As for what's causing it: lightmaps. The lightmap that's right on the edge of that displacement is looking straight into the sun and so it gets fully lit.

Sewing the edges of the ground displacement and the wall displacement together should also fix it, right?

Yup, but it won't look as pretty. Right now you have a clear distinction between wall and floor. With one continuous displacement you don't. Looks too smooth.

You can still sew it while having a right-ish angle between the floor and wall. You don't have th smooth it, it wouldn't look any different to what OP has here.
