Here's the parameter dump:

RAW noise reduction, unfortunately, won't help in my case, since my
original is a JPEG. Shooting RAW isn't very practical at a game where
I might shoot 2500 frames.

Try NeatImage it's the best I have found at de-noising non raw images and
its available as a standalone on linux for free. It also makes use of opencl
/ cuda capabilities so it's quick.
Regarding NeatImage, apparently a Dutch company :
https://ni.neatvideo.com/ says "the most advanced noise reduction
algorithms in the industry."
https://ni.neatvideo.com/overview/how-does-it-work links to
https://ni.neatvideo.com/download/noise-profiles although it looks like
there are less profiles than in darktable (well, for Nikon at least).
Strange and heavy format.
Speaking of good non-free noise reduction software, how about DXO Optics
Pro, then? (Not for Linux, though).
I've seen impressive demos of their PRIME denoiser in the past (and the
denoiser before PRIME). Explanations on the current site boil down like
profiled non-local means, so the secret sauce must be elsewhere?
