So why is is that it seems the W Chesapeake Bay has so few beaches compared to other coasts like the Atlantic, the Long Island Sound, Delaware Bay, or Gulf Coast?

One reason is that shoreline protection structures/measures used over the last seventy years or longer have restricted the sand replenishment of sand on the beaches.

Those structures would include rock revetments/seawalls (which replaced wooden seawalls), concrete seawalls and wood or stone jetties. The latter trapped sand but starved the beaches downstream.

The approved method for shoreline protection now, which replaced the stone structures are Living Shorelines:

As mentioned, you also have the constant sinking of the Bay shoreline due to the rebound of interior land masses north through Pennsylvania returning to pre-glacier outlines.

So it's geological? How exactly does PA relate, and why then is this not an issue on the Long Island Sound or Gulf Coast?

Whay are you now asking about PA? Do you mean Pennsylvania.

Long Island beaches are eroding:

As are the ones on Delaware Bay but ocean erosion of beaches sucks all the oxygen out of that discussion.

And also on the Gulf Coast:

What I am saying is, on just about any other long coastline there are ample beaches, but not so much on the western Chesapeake, why?

A couple of us, including me, have already given you some of the answers accompanied by links to analyses and governmental agencies. What more do you want?

We could have a technical discussion of littoral drift if you like, which is a component of both beach replenishment and erosion on the Chesapeake.

So basically it is because the CB developed rapidly with an asteroid versus the usual glaciation process or plate tectonics?

No, not directly.

If you are truly interested in a detailed technical discussion of the dynamics of Chesapeake Bay Virginia shoreline morphology, this is an interesting read even though it is over 20 years old. The study was jointly commissioned and carried out by the Commonwealth of Virginia, the U.S. Army Corps of Engineers, and the Virginia Institute of Marine Science.

https://scholarworks.wm.edu/cgi/view...ontext=reports

There is a 2019 follow-up funded by the Virginia Institute of Marine Science. It tries to look at the efficacy of recreated pocket beaches and marshlands to manage ongoing shore erosion due to rising sea levels, which was not popularly viewed as a major concern when the first study was written.

Thanks, so these will help explain why the CB has relatively so few beaches compared to other US coastlines, like the Long Island Sound, Gulf Coast, etc.?
