That’s two cancelled classes…. Seems they’re not sure what they want or can’t hold to a plan. Why not keep building Burke class ships and use missile systems to handle shallow water action. Or drones, possibly gunships with standoff capability.
Before the costs exploded, the Constellation class frigates would have been half the cost of Burke. There are jobs that need a warship, like patrol off Yemen, but the LCS don't have the defenses.
Also, this is not a good sign for Navy ability to build the DDG(X) which will be the successor to the Burkes.
Its air defense would have been pretty potent. It had the same Aegis system as Burke. The only limitation is it had the medium range Standard instead of the long range one.
The big recent change in naval warfare is that anti-ship missiles have gotten common. Ukraine used locally built ones to sink a Russian cruiser. Yemen and Iran have been making them.
