What do you think is Buffy’s real astrological sign spiritually?

I know she’s by default a Capricorn but that’s just because her birthday was set in January because that’s when the WB wanted to move to Tuesday nights and it became her official birthday from that point on. But I don’t think Joss created her character with astrology on his mind especially since most Capricorn stereotypes (hard working, professional, career oriented, competitive) are not as Buffy coded as stereotypical traits other signs have, which are way more Buffy. To be fair I would argue season 7 Buffy is very Capricorn. But especially like in the first 4 seasons I don’t see it as much as others

So I’m curious on everyone’s thoughts- if we never knew Buffy’s birthday or had the canonical knowledge that she’s a Capricorn what would you guess her astrological sign to be based on her character you’ve gotten to know over 144 episodes.
