I have recently started a new game on Goat4521Cheese (already on your list) and can confirm 3 crossroads in addition to towns and cities mentioned.
For anyone else undecided on a new seed, this has been an amazing start for me on this map.
Had horde defenses in place by day 6 with functional mine, day 11 have tunnel leading to another nearby mine with abundant sources of coal, nitrate, lead and iron along the way.
Have work bench, cement mixer and mini bike. Only missing 2 beakers for chemistry station.
Also have a farm growing potato, corn, blueberry, yucca and aloe Vera. Mushrooms growing inside.
On track to have horde defence upgraded to concrete for day 14.
Will be happy to share any coordinates that I have at this point.
