Epiphyllum oxypetalum, queen of the night, night blooming cactus/cereus, developed these tan, white, beige rough spots. Spreading to different leaves. Still producing new leaves. Is this something I should be worrying about?

It is hard to say without seeing the damage. My best guesses would be fungal/bacterial infections, or possibly scale insect. They both fit your description in different ways. They also have very different treatment from each other.

You will treat the first with a fungicide. This article will help: https://www.gardeningknowhow.com/garden-how-to/info/using-fungicides-in-garden.htm
