When you use the "match ip address ..." line under the route-map config this ties the route-map to an access-list. So when the route-map is referenced routes must then match an entry in the acl, or if they don't they simply don't get redistributed.
Control plane is responsible for establishing routing neighborships and exchaning routing information. Also responsible for building the routing table.
Data plane is responsible for forwarding the actual traffic and uses information supplied by the control plane to do that. Note if process switched the packets actually go to the control plane to be forwarded. If fast switched only the first packet goes to the control plane. If CEF switched no packet go to control plane.
Traditionally access is restricted using acl's / PBR which control where traffic could be/should be sent. But using these is not supplying separation between the control and data plane ie. there is still one global routing table in use.
VRF's which are being used more and more allow for complete separation between the control and data plane so there is no longer one global routing table in use.
So practically the difference is
You want to allow a certain vlan to only be able to access one server vlan.
You want the rest of your vlans to be able to access any other vlans.
You can implement this with acl's/PBR but it is a lot of administration and can be prone to error. Alternatively you can use VRF's so that the router/L3 switch now has 2 routing tables which are not visible to each other. The routing table for the vlan that is restricted only has a route to the one server vlan. The other routing table has routes for everything.
MPLS VPN's and VRF-Lite use VRF's for control and data plane segregation. VRF's in effect allow you to create multiple virtual networks on the same physical infrastructure.
