Do you know if, when you are facing the sun when it appears highest in the sky from your location in the northern hemisphere, on the equinoxes, you are facing due south or southeast?

I am pretty confused. I am a park ranger and am trying to make sure I understand the concept of equinoxes, and specifically, why the sun rises due east on any horizon on the equinoxes. I'm trying to simplify for younger audiences, without mentioning the celestial equator. My thinking is this (I'm going to have visuals for the younger audience, so this sounds more complicated than it will look): If the north pole is tilted directly towards the sun during the summer solstice, and directly away during the winter solstice, the equinoxes are when both poles are tilted 90 degrees from the sun. So looking at the spots where sunrise is occurring on Earth, which are the spots 90 degrees away from the "noon spot" (where the suns rays are hitting earth directly), there is a line of longitude connecting both poles, running north to south, which appears to stand straight up (if looking directly at the line of longitude where sunrise is happening), meaning lines of east and west point horizontal (rather than at some diagonal angle), directly at the sun, meaning all lines running east west at the locations experiencing sunrise are pointing towards the center of the sun. Is there something wrong with this? Because I've heard that in the northern hemisphere, when the sun is at its zenith, it is pointing due south. If the way I explained it is correct, it seems like on the equinoxes, during solar noon, your line of longitude will be diagonal (if viewed so that the spots experiencing solar noon from a vertical line) so the spot on the equator experiencing solar noon at the same time as you won't be on your same line of longitude, but will actually be east of it, meaning the sun at its zenith would point southeast. Where am I going wrong in my thinking about all of this? I hope I explained that somewhat coherently.
