As you can see, it degrades pixel quality substantially, but makes for a much crisper image at 1000px.
I use a 9px high pass at 80% opacity, followed by a 1.2px, 60% 12 threshold Unsharp Mask at 40%, then downscale using SinC interpolation.
For very sharp film (ie Rollei Retro 80s, other tech films) I will scale back the high pass radius, and leave more USM opacity, for a very blurry or grainy shot I will go the other direction.
For massive files, ie any stitched MF past 645, I will use the same sharpening, but pay more attention to the downscaling, often I will go to 2x desired vertical resolution, gaussian blur between 0.5 to 1.5px, then scale to output res, to soften the jaggies.
