There is no best finish — there is the finish whose trade-offs match your project. Weight the six criteria and we score the ten workshop standards against them.

| Waterborne polyurethane | 4 | 4 | 4 | 1 | 5 | 3 |
| Nitrocellulose lacquer | 3 | 3 | 2 | 4 | 5 | 2 |

| Spar varnish | 4 | 5 | 2 | 2 | 3 | 2 |
| Hardwax oil | 3 | 3 | 5 | 5 | 4 | 4 |

Ratings 1–5, editorial — structured from the trade-off literature (Flexner, Understanding Wood Finishing). Film finishes are generally considered food-safe once fully cured; the food column rates how directly each finish is sold and documented for food contact.
