I use Cascadia with it (I know, poor license compatibility microsoft bad yadda yadda), and it goes together quite nice besides the inconsistent weighting.
Under what OS? I find Cascadia Code on macOS very thick, almost like a bold font.
I'm on Linux, using subpixel antialiasing (very similar to Mac) and I've had the same experience. I do appreciate the thickness, but sometimes I switch it to the light/mediumlight to match it with my system font (Inter)
