Sharpening should be after upscaling or before downscaling.
Upscaling sharpened video can be "upscale" artifacts caused by sharpeners.
Same for levels/colour correction.
Also I think cropping should be done before resizing. Black borders can be recognized as line then there can be ring/halo artifacts.

So my recommendation is
deinterlace -> denoise -> deblock -> cropping -> upscaling -> sharpening -> levels+colour correction
