Shellac may be enough on it’s own, it’s underrated (IMHO) as a final finish and much better than many give it credit for. It’s colorfast and easily repaired if it is damaged, so give it some though. If you do choose to top coat it with a water borne (or poly-anything that’s oil based) be sure to use dewaxed shellac.
