So all of the packages will allow you to spark into an npc character, and potentially inherit a farm from your parents as long as you both spark into a farmers child and curry favor long enough they will the land to you.
That being said Bloodline+ is where you will get access to exposition and some EP to spend on various things, such as a plot of land, buildings to place on same land, some startup equipment, etc. Example prices here
So if you want to start of the game with assurance some specific plans you have in mind are achievable, then picking up a bloodline package and maybe some extra EP on top of it is the safer bet.
