You need to use Z forward and Y up for Unity. When I use this my world in Blender and Unity is aligned.
As for the rotation values that means you have rotated the object in OBJECT MODE inside blender and havent applied that rotation. I’m assuming you are using .fbx (?) and in that format if you want to apply OBJECT level transformations you have to click the “EXPERIMENTAL apply transformation” otherwise the object will carry over its transforms (you can apply them inside blender by ctrl-A I think)
When I have transformations probably applied in blender, and use Y up Z forward my exports to Unity go smoothly.
As for if you still need to rotate the object orientation for some reason as DanPool said only way I know is first rotating the object to the orientation you want in OBJECT mode, then go to EDIT mode select all vertices and rotate it back to proper orientation. This way you’ll have changed the objects local coordinate system while maintaining the visual orientation of the mesh.
Hope this helps Good Luck.
