Hot take to avoid frontloading the classes with too many choices at 1st level for new players:
Write the ''main'' archetype of the class as part of the main class chassis in the book, not in a different section after the class chassis. Then make archetypes who swap those class features with the ones from the new archetype.
ie: The Hunter becomes part of the base ranger chassis at level 3-7-etc
After the class write up, you have the Beastmaster archetypes, which goes like: ''A player preferring to adopt the archetype of the Beastmasters loses the X-Y-Z features of the Ranger and gain the follow A-B-C features instead.
So players who are not at-ease with making a bunch of choices just pick the base ranger, already all written in the book while a more advanced player can look at the alternative archetypes features.
