I'm pretty sure I'm right about the planets. The planets are aligned that way. If you're experienced looking at them with binocs, you should be aware of that. The line the planets are on is known as the ecliptic.
You are right. I do think it is miraculous that the trajectory happened to bring the capsule into a solar eclipse and Mercury, Mars and Saturn are positioned in this way. This site helped me understand the current/past positioning[0]. Even though there is no reason the photo has to be oriented with the planets to the right. I am still surprised at how blurry they look when zooming given what I see from Earth with binoculars. I guess they are magnifying considerably more than this lens.
In retrospect it was pretty silly to think they could have been galaxies.
I think we're seeing issues of refraction from shooting through the windows of the capsule. That's causing the glowing or blooming effect from the point light sources. What I thought were possible galaxies look more like distorted stars from the refraction. I finally found a higher resolution image. All of the brighter point sources have that diffraction. It looks like some trailing of the stars as well.
That link is a nice visualizer. On the day of, the live cast announcer stated we were seeing Venus in the feed from the GoPro. But that seems incorrect, and it looks more likely to be Mercury.

Also, if you look at the famous family portrait, you'll see they're in a pretty straight line as well
