Pick the Xperia 1 VII if the display is what you stare at all day — refresh rate, brightness, or sharpness is where the difference will be most visible. The biggest gaps in its favor are weight, pixel density, headphone jack.
Pick the Xiaomi 15 Ultra if you photograph or shoot video regularly and want the better imaging pipeline of the two. Its strongest claims are wireless charging, wired charging, front camera, among others.
