Lived beside them all my life so I'll have a go!

I'll agree with Mateusz that concrete & boulders aren't a beach - a couple
of those examples I'd probably call man_made=groyne + natural=rock (& yes,
that's because it then renders as rock!), however you can have (isolated)
boulders on a beach.

What is a beach though is a bit tricky, especially for OSM.

It would usually be "the area above the Low Tide mark" but that then
clashes with OSM Coastline, which is taken as the High Tide mark, so that
would then have to mean that the beach is

"The area between the High Tide mark & any adjoining vegetation /
structures / landforms". It's usually largely unvegetated (but may have
isolated trees, clumps of grass etc), & is made up of natural materials
such as sand, pebbles, shells etc"

How's that sound?
