How to select all the faces inside surrounding sharp edge faces?
Below is simplified example: I am trying to get all the faces of the pane inside the sharp edged window frame of the car.
Shift+ and Shift+G (all options inside the menu) don't work.

It has to be said, the topology of your reference model will give you a hard time. There's no getting around it. Selection will be difficult, shading might be affected; the interpolation of normals across surfaces won't be very predictable. Re-shaping parts will be nearly impossible.
In a more conventional topology, like this:
..the flow of edge-loops / quad face loops follow the 3D form, and will help you all the way. Selection tools are built for it.
In the mean time, you could try Select Linked : Flat Faces, adjusting the angle to catch the boundary:

Hover over faces to select and press L then select Sharp in the popup that appears in the lower left corner.

$\begingroup$ Thank you for reply! I need to mark the seam first in this method. Is there any way it can auto detect sharp edges in just one selection? $\endgroup$– Quan LeeCommented Dec 19, 2022 at 15:27
