95437354 is the accumulator fitted to Hydroactive and Activa Xantias. No idea how it is different.
96178589 is correct for 2.0i all years and all non-Hydroactive Xantias from 96 on. It is 55 bar compared to the 50 bar originally specified for your car, so should give a slightly softer ride.
N45332s are also 55 bar, so should be equivalent to the spheres you removed.
Sphere types?
