Well… there is a dtstyle (for darktable) entitled 60s image,
which might be relatively close to what you are looking for: https://dtstyle.net/
Apart from that: isn’t there a HaldCLUT (for rawtherapee) performing something similar?
The yellow tinge you prefer presumably comes from natural ageing of the paper the images were printed on.
Have fun!
