Naval gun support is now largely redundant. The conventional wisdom is that it is far too dangerous to bring ships in that close to a hostile shore, and as you say, most of them dont have the gunfire to make it worthwhile anyway - all the more so because modern land artillery emphasises volume of fire whereas naval artillery stresses accuracy. Naval strategists have now largely delegated land attack to rockets, bombs and precision munitions from aircraft, although the recent development of stand off guided land attack missiles like tomahawk has seen direct naval fire support make a bit of a comeback. Really though, these precision guided land attack missiles are far too valuable to be used on anything other than high priority high-value targets. Direct support of say, an amphibious assault by suppressing beach defences, would almost certainly be done by aircraft.

The RN used naval gunfire to suppress artillery and destroy at least one Libyan convoy. I wouldn’t say it is redundant, especially considering that a ship can carry a hell of a lot of cheap shells and only a limited number of very expensive guided missiles for hitting prolific but dangerous enemy targets...
