If I read you correctly you should for now stay away from the 11-16, 12-24 range. The wide angles you've refered to in your PNS days would be in the range of 24mm DX or 35mm FX. 11-16 and 12-24 are in the specialist ultra WA area and would take some practise to learn to use, and for environmental-story telling family shots, your likely range is in the 18mm to maybe 70mm range.
Your 35mm f/1.8G would be similar to 50mm on FX, and will continue to be tight for small spaces, like try to get the whole table in during a dinner.
If size is a constraint, you can, and perhaps should, get a 18-55 which sells for peanuts (not the NKF type) at BNS forum. Use it mostly for the wide end as an 18mm f/3.5 indoor and pop up your flash, and balance your ambient using M mode and boost the ISO to 800 or 1600 for those table shots. Continue with 35mm and 50mm for your portrait.
If you don't mind a slightly larger size, then the 18-70 would be a better choice, a bit pricier than 18-55 though.
Personally I mostly keep my 18-105 for functions where I may need the "reach" of 105 without changing lens. But will use my 18-70 when I am out and about, with other lenses as necessary. I have the AFS35 as well as the AFD50, plus others like 60 Micro, 105 Micro, 10-17 fisheye, 10-20 UWA, 70-300ED, etc.
