Untick 'Use Space Transform' and use '-Y Forward' and 'Z Up' in Blender FBX export settings:

Blender Export Settings

If you are also exporting Armatures, set the Primary Bone Axis to -Y and Secondary Bone Axis to -X:
Blender Armature Export Settings

In Unity use the Bake Axis Conversion import setting:
Unity Import Settings
