Given the crappy (crf 28) source.
You will definitely lose some more 'details' since, even when looking at that manually, I often can't really tell what's artifact and what detail.
If possible, you might want to use 10bit encoding as intermediate to avoid some of the banding.
About filtering this mess:
a. try to find a mask i.e. LumaMask with Limit 100 (or higher) with which you can limit what you want to get filtered
b. then try some strong masked denoising
c. maybe downscale to 1080p and apply all filtering after that.

Ps.: if machine learning is an option, downscaling to 1080p and applying SCUNet might be an option, to get it somewhat better, i.e. https://www.mediafire.com/file/ygh6h9wpy...y.mp4/file
