hi Bill! I looked through previous answers about Eevee, but saw nothing that spoke of how to know what kind of signs they might show for their preference in evolution. Is there such a thing as Eevee who like warm weather would rather evolve into Flareon or Eevee who like swimming evolve into Vaporeon more often, or is all of that just a myth? And what are the signs for a Sylveon preference, if there is such a thing?

Absolutely, there is such a thing. These are often the first signs of interest in a particular evolution. Usually, these signs will evolve (forgive the pun) into more overt signs, such as an eevee fascinated by fire, one delighted by thunderstorms, one who won’t get out of the water once it gets in, one who’s more nocturnal than usual, and so on. Also watch out for signs of excitement at the sight of the eevee’s chosen evolution or attempts to use moves of a particular type. A strong preference for using moves of a specific element is usually an indication of a particularly strong preference for a specific evolution.

Regarding sylveon, the signs are very similar (an eevee with a preference for fairy-type moves, sylveon, or pink/soft/lace-covered objects will likely want to evolve into a sylveon), but it’s also about personality as well. An eevee that hopes to be a sylveon will show more affection to its trainer and often responds more enthusiastically to treats, even more so than eevee intending on becoming espeon or umbreon. Unusually strong protectiveness is also a pretty good sign.
