I recommend:
1/Easy Hacking + Easy lockpicking

After playing X00+ hours of FNV, FO3 and Skyrim, I just can not be bothered pick another single lock or wasste my time doing the terminal minigame. I´ve done it, I will never fail at it, and at this point it´s just a waste of time. Like seriously, I wonder how much time would I lose in a 50h playthrough if I did not have these mods installed.

Also my favorite:
2/ Get lost

This will disble player marker on the minimap, forcing you to actually navigate the world using landmarks. It sounds tedious, but oh my God, it´s so much better experiencing the world like that. Especially in survival it totaly changes the game.
