Unsure what you mean by modern. It is challenging to recover the original colours because (1) I am unfamiliar with slide film and (2) this slide is very old and faded.
Thanks for sharing the context. I wonder if this residential area still exists. If so, someone could scout the area and take reference photos 
.

Couldn’t outdo the colours the others output, so I decided to take the B&W route. (I might come back to it: I have several strategies that I would like to explore.) Here is the first of the two B&W takes (edit: the second isn’t ready yet). Enjoy!
B&W
1 PhotoFlow → linear Rec.2020 (no clipping) → rotate.
2 gmic → interpolate bad pixels → output multiple B&Ws.
3 enfuse → combine to output one B&W to rule them all.
4 gmic → interpolated bad pixels → discard alpha → brighten → sharpen (tones) → resize → sharpen (edges).
