I'm not convinced by this idea of "more interesting" ingredients. Sesame oil is interesting, but that it's certainly not a better choice for this purpose than a neutral oil of some sort. Sometimes plain white vinegar is the right flavor, even if others may have more personality. This is the attitude that gets us constant Romaine lettuce and microgreens, when the freshness of iceberg lettuce is one of life's great pleasures.
(I'll give you fresh-made mayonnaise — I can't think of a time I regretted that, except when it came time to do dishes.)
