I wouldn't overthink it. You can compliment people on beauty, and I think the solution is actually to find MORE varied types of beauty than the norm. So yeah a white thin supermodel might be beautiful, but so is a Black grandmother smiling at her grandkids, so is a middle aged Asian dad laughing at his daughter pretending to be a dinosaur, so is a small boy sounding out words for the first time, a teenage girl lost in a book etc. Beauty is everywhere. The problem is that society has limited the definition of beauty. But it's everywhere - in nature, in the spirit of all life. In love most of all. In happiness. Even in sadness. Beauty is truth and truth beauty. That's not a trite saying, it's not meaning it in the sense of "an airbrushed model is truth", it's meaning true beauty.
