Searching by mesh, not object name

Question

I am exporting an fbx with tangents, but I am getting this error on export for some of my mesh objects:

These errors are not referring to the object name, instead the mesh name found in the object data properties panel. It seems this cannot be searched in the Outliner, which only searches object names, which are not the same as the mesh names in my case. Is there an easy way to find these objects by mesh name or select them via python?

Select Mesh Objects with ngon faces.

XY Problem. The issue with the exporter is ngons ie meshes with faces using more than four vertices.

Rather than search for anything by name, instead will search by trait. Here is an example script to select all mesh type objects with 1 or more ngon faces in their data.

import bpy

context = bpy.context
scene = context.scene

for ob in scene.objects:
    ob.select_set(
            ob.type == 'MESH'
            and any(len(p.vertices) > 4 for p in ob.data.polygons)
            )

Evaluated mesh,

If applying modifiers is selected in the exporter, doing same on evaluated mesh

import bpy

context = bpy.context
scene = context.scene

dg = context.evaluated_depsgraph_get()

for ob in scene.objects:
    ob.select_set(False)
    ev_ob = dg.objects.get(ob.name) # hidden obs not in dg
    if ev_ob is None or ev_ob.type != 'MESH':
        continue  
    faces = ev_ob.data.polygons
    ob.select_set(
            any(len(f.vertices) > 4 for f in faces)
            )

The next thing to consider will be how to deal with the ngon faces, eg could poke or triangulate, ngons to make them tris.

One option would be to append a triangulate modifier instead of select

    if any(len(f.vertices) > 4 for f in faces):
        ob.modifiers.new("Tri", 'TRIANGULATE')
