The suspension isnt really much different interms of type. Forged lower front arms though.
The comment about comparison to FN2 handling may be from the CofG being 15mm lower, also the seating position is lower aswell along with a lighter powertrain in the nose and a shorter wheelbase. They both have EPAS so not that last word in feel.
That said its no difference to a Clio 182 etc either in terms of suspension architecture, just comes down to tuning.
EP3, DC5 and FD2 all retain the mutli-link rear suspension at the expense of package space, euro market cars seem to want the large family hatchback. The Civic is testament to the other side of its beam suspension, the boot is very wide and the floor low.
Interestingly the Jazz (Fit in the states), which is the same platform as the Insight 2 and CRZ (shortened) has the twist beam rear end but the Honda Fit EV has multilink suspension and rides much better for it, even on an EV product.
CRZ is an interesting car for UK roads, slow enough to have fun and explore and enough grunt to allow steering on the throttle.
