24-70mm f2.8G vs 24-120mm f4G vs 70-200mm f2.8G

Hi all, I would like to get some of your opinions from those who uses these lense for your photography. I'm mostly shoot landscape, architecture, portaits, night landscape/portraits during holiday trip. I've owned a 14-24mm f2.8G and a 50mm f1.8G lenses which i think it able to cover for landscape and portraits.

Hence I was thinking into consideration whereby if I would like to took certain close up architecture and portraits shot where distance is the constraint and zoom is require. May I know which of those 3 lenses are recommend for my shooting style.

As what was in my mind is 24-120mm f4G has a sufficient zoom for me, however, its constant f-stop isn't create a sufficient shallow DOP for portraits where shooting distance is a constraint for close up architecture isn't a problem.

24-70mm f2.8G however, not too sure whether does it able to covering my desire shooting distance, otherwise will go for 70-200mm f2.8G but between 24mm to 70mm i do not have a covering focal length other than the 50mm f1.8G

Any opinion?
