Network segmentation project

Hi all, 

I am in the optics and the reflection to start the project of segmentation of my local network.

i have xg 330 as edge firewall

Si i think about to methods, go with L3 switch for inter-vlan routing or don't make L3 switch and do all the segmentation with the XG

i don't know if there's limitations on xg to do segmentation, and i don't need to manage ACL inter-vlan on L3 switch

So i ask is sophos xg have the capacity for this type of project, the prerequisites and the constraints that I may have.
I know that everything depends on the need, but the topology is not really complex, it's classic

thanks
