I don’t have a final position on this personally. For whatever reason I gravitate toward a “traditional” burial. I am not strongly opposed to cremation. I wonder if adherence to a position of traditional burial is that it feels like a more respectful, less destructive, treatment of the body. Believers knowing 1 Corinthians 6:19-20, Genesis 1:27, etc maybe feel it’s more in line with respectfully “preserving” what God created. I don’t know. We all know inevitable decay reverses it all anyway.
