Finally made some progress with shadows: It turns out shadow resolution is directly tied to r.Shadow.DistanceScale, with lower bringing higher res shadows. Of course, the downside is that the draw distance decreases. I can't seem to find any way majorly improve shadows outside of lowering distancescale, after trying out countless options. Regardless of the DistanceScale, I'd recommend keeping r.ShadowQuality to either 2 or 3 - ShadowQuality only impacts the filtering of shadows, and with the low resolution shadows available, the higher level filtering does more harm than good (1 means no filtering, which is just as bad). 2 provides sharper shadows, but 3 animates smoother. Hopefully someone can find a way to work around this.
Another issue I couldn't fix was TAA ghosting - no matter what TAA settings I used the ghosting was just as evident. Thankfully its not too widespread an issue.
