I think I've tracked down where this is mainly happening. In the onChangeNetworkStatusEvent it checks whether you have data saving on OR if your video autoplay is set to only wifi. If either of those are true it'll call refreshAdapter() (link) which for some reason gets the closest previous post position and forcibly scrolls to it (link).
I've confirmed this by setting my video autoplay option to Never (data saving settings were already off) - this fixes all three issues detailed in the OP (scrolling in comments, feed, and carousel position).
The linked lines of code are just from PostFragment but the same behaviour seems to appear in CommentsListingFragment and a couple other files as well.
My hope is those can be changed to stop forcibly scrolling or resetting image carousels as it makes for a super frustrating experience to bounce around while scrolling in an area with spotty wifi.
