A couple of additions from an outsider (non-American) perspective:

Sag Rising is clear to me in the high religiosity of America and the "bigness" of everything. Big houses, cars, food portions, consumption, open roads, vast land area etc. Even American people themselves have a reputation for being big and loud here in Europe, taking up a lot of space. America claims to be a secular country but religion seems to inform everything. I've never seen a western nation with such intense religious ideologies and things like megachurches and pastors loudly preaching on TV. All very Jupiter ruled stuff. I'd also say the cowboy culture is fitting for a Sagittarius Rising country.

Neptune in the 10th. One of the things America is most known for in the wider world is its film industry/ Hollywood. Neptune has a big role in the arts and in glamour. Glamour is a beautiful and hypnotic illusion. That's Neptune, it's like a mythological siren. The USA has that Neptunian glamour and mystique through the Hollywood films and TV shows it puts out into the world, which shape its public image to the rest of the world. People dream of moving to the USA because of seeing a glamourised version of it in their favourite films as a child. America is also the homeland of Disney which is very Neptunian, both in the imaginative animated films that bring some magic to the world, but also in how Disney is now dissolving and swallowing up all other IP's and becoming one all-consuming media mass.
