I don't know what stackable wall pavers are.
Garden wall blocks would be stable, but a bit thin. I can't
imagine them looking good on the back side.
Keystone or similar will break the concrete at about 80# per unit
and I can't imagine them looking satisfactory on whatever is the
back side.
Win, lose, or draw, take Rico's advice and keep the wall off the
slab or excavate under the slab edge and improve the bearing.
