The Sims 4 Story Progression - Help the Gurus

The lack of Story Progression is the main reason I have not bought TS4.
The bare minimum I would need to make me interested in this game is for unplayed Sims to be able to form romantic relationships with each other as early as the teen stage, and to be able to marry, move in together and start having children of their own once they become YAs.
I'd like some toggle to set which ages may romance each other, so you wouldn't have recently widowed elder Sims pouncing on YAs that had just graduated high school (A problem I had with awesomemod's SP mod for Sims 3. Twallan's SP allowed you to restrict the romantic interactions between age groups)
Unplayed Sims should also choose careers based on their traits, and pursue the skills they need to progress in them.

Ultimately, though, for people who like to play neighborhoods for extended generations, you will need to make the towns much larger or we're going to run out of housing by the second generation. In TS3 with is much larger hoods (SV had more lots than the two base game TS4 towns combined) you'd start running into housing problems by the 5th of 6th generation. With the tiny TS4 towns, I can't see getting past the 2nd generation. I know this is not a Story Progression issue, but it does go hand in hand with the idea of having and actual living town for your Sims to inhabit, which is the main function of SP, and the reason I won't play a Sims game without it.
