Land Based Soft Plastics Rod Advice - Atomic Arrowz, Shimano Raider, or Daiwa TD Hyper?

I currently have a 6'6" 3-5kg rod and looking to get a lighter rod for soft plastics fishing for fish like bream, whiting, flatties.

I've narrowed it down to these models, all around the same price range.

Specs below:

Rod	Cast Weight	Length	Rod Weighting
Atomic Arrowz Estuary AAS-270UL	3-14g	7'	3-10lb (approx 1.3kg-4.5kg)
Atomic Arrowz Estuary AAS-270SUL	2-10g	7'	2-6lb (approx 0.9kg - 2.7kg)
Shimano RAIDER 762 BREAM SPIN	3-12g	7'6"	2-4kg
Shimano RAIDER 722 LIGHT BREAM SPIN	1-10g	7'2"	1-4kg
Daiwa 23 TD HYPER 702LXS	2-10g	7'	1.5kg-3kg

The issue with my current rod I feel like is that I'm not able to flick the light plastics as far as I want and I'd like the small fish to feel more like monsters when I'm trying to reel them in. Right now kinda feels like I'm just skull dragging them in a lot of the time even when I try to set the drag a little lighter.

I see the common advice is a 7' rod too - being land based, would even longer rods like 7'6" be even better for land based? Trying to understand why 7' is the common recommendation.
