Your only option is a hook to swag the light into the proper location

Conduit painted ceiling color

A very simple "medallion" They are at any home depot. Or on amazon

And for a few inches? I'd forget all of the above. Mount the light and be done. Move the TABLE " a few inches"

I would not call attention to the fact with a medallion , That table needs to be scooted over further from the counter anyway so do that first then see if you need to do anything. You could look for fixture that goes in different directions instead of all centered

I'm working with a small space. moving it over will run into the couch and rug.

Put in a drop ceiling the same length of your table over your table. This will hide your wires and original electrical plate.
