I'm not sure what to say. Usually, if you didn't like Fallout 3, I would say to stay far away from Fallout 4. However, it has much the same core as Skyrim, so I'm not sure what to suggest.
I will say that Fallout 4 has a massive amount of content, much more than Fallout 3 or Skyrim, so there isn't much question about having nothing to do. It features settlement building, which is mostly what you need junk for, but you can skip that if you want to avoid weight issues. Just pick up valuable pieces of armor and weapons plus junk items like tape and oil that you need for upgrading your gear.
You could also make it more 'Skyrim-like' by going with a melee build. Strength has the added benefit of letting you carry more stuff.
It's absolutely not a hand-holding game, though. It's for people who like to explore and find hidden locations and gems.
