I'm seeing you've given .mw-indicators #mw-indicator-coordinates order: 1 so that's higher than all the other indicators so pushes it to the right. If you want to push it to the left, maybe a generic rule with overrides for positioning of coordinates would help such as :
.mw-indicators #mw-indicator-coordinates {
order: 1;
}
.mw-indicator[id] {
order: 2;
}
For T337604, I don't think it's possible to have indicators on special pages, so it should be okay to display: none it as you suggest.
#firstHeading { width: 100%; }
should also be safe.
Regarding English - I believe indicators appear in the order they are added to the wiki page by the parser so it can probably be edited in such a way that featured becomes the last if necessary. Something like #mw-indicator-featured-star { order:99;} would also likely guarantee it to always be last if necessary.
