When I use the following command, the result is as follows, which xresolution and resolutionunit should I take?

I would take the one that ExifTool shows without the -a option (ie. IFD0)

I'd say it depends upon which one is used by the programs in your workflow. Photoshop, for example, might prioritize to the ones in the photoshop block.
