which schemes are more stable for compressible transient with shock &high gradients?

i have a compressible unsteady with moving shock and expansion fans that have high gradients especially near walls.
What schemes for different parts are better?for instance is backward better for ddt?or SFCDV for flux that i think maybe is better.am i correct?
What about other schemes for grad,div,etc?
Thanks for consideration.
