Hello, and welcome to the community, Whiteslag.
If you want to see all the Angelica Kingdoms (NA-West), then check out this thread where all of them are listed. There really isn't any hurry in picking a Kingdom at this time, but it would be good to look in your spare time to see if the community fits well for you.
Be wary of anyone making promises to you, as nothing is guaranteed with the game still in Pre-Alpha development. Take your time, lurk around, ask questions on how they run things structurally or ideally.
For packages, I recommend Bloodline ($135), it's the basic Gentry package and has access to Exposition which it gives players a three month period to set up their domains, settlements, area, etc.
