How does using a FX lens on a DX body affect the sharpness of images taken with that combo? I see where the DX in a FX body results in a smaller overall image, but have not seen comments on the sharpness of images taken with FX lens in a DX body.

Works fine -- a good lens will be a good lens on either body. The DX body will use only the central image from the FX lens and so if the lens is otherwise a tad soft out in the corners on an FX body you won't see that used on a DX body. I have and use many FX lenses on DX bodies.

The two I use most are my Sigma 150-600mm and my Sigma 150mm macro, both work brilliantly...had many pics published Nationally and won several awards as well. I also have this one, great...
Sigma 35mm f/1.4 DG HSM Art Series Lens.
Sadly the 150mm macro is no longer made...
The only issue is that the FX lens might be larger or heavier than a comparable DX lens. Optically, however they work just fine. Since Nikon never really fleshed out their selection of DX lenses and what they did do were primarily consumer zooms you will likely encounter higher quality than you are used to.

Not all of them works great on the smaller sensor.
The Sigma 70-300 F4-5.6 DG is ok on FX but is soft on a DX camera.

I use mosty FF lenses on crop bodies.
They work just fine and produce great results.
Use FF lenses all you want with no worries.
FX to DX isn’t problem. Thom hog ( I don’t know exactly his name) and Ken Rockwell writing about lenses just google it

It may very well be an improvement. If an FX lens shows vignette (almost all lenses do) or so-so edge/corner sharpness on an FX body that will be "cropped out" on the DX body. The central part of the image is usually the best a lens will offer, FX or DX. The only advantage DX lenses offer is a smaller size and weight...largely due to more plastic used in the DX design and smaller glass elements. Keep in mind, lots of factors affect sharpness.

Typically, DX cameras have a smaller pixel pitch (AKA greater pixel density) than FX cameras - but ultimately depends on the EXACT cameras we are talking about.
Anyway, the camera with more pixel density will reveal more lens limitations/deficiencies - so the images from the camera with less pixel density will look "better/sharper - again, which is typically FX.
Because DX crops off the less sharp corners of the FX image, the corners of the DX image should seem sharper than the corners on the FX image. Keep in mind there are a lot of variables coming into play here !

Yes, as a rule, as the FX lenses offer a wider aperture for comparative same focal lengths. It is not by accident that you never read of a person buying a full frame camera and to save money purchasing DX lenses. My full array of Nikon FX lenses initially was used on a DX D7100. Under near great to great lighting, the images were very good. The D7100 is not a good low light camera. Upgrading to D850 made all the difference in any light. Here is another spin – invest in the speakers not the receiver. When I converted to full frame body, my investment was protected. Additionally, my D7100 and my only DX lens (18-300), is with me always.

it doesn't affect sharpness.

If the lens is sharp on a full frame body, it will be sharp on a crop frame body. In fact, since the crop frame sensor will be seeing the center of the image circle produced by the full frame lens, one should see better sharpness across the frame.

In theory, I guess, you may have some gain in sharpness when using an FX lens on a DX-sensored camera. Most lenses, regardless the format, tend to be sharper in the middle of the lens, and fall off some toward the edges.
At greater enlargements, you could likely pick out fall off, comparing a 4x6 print with a 24x36 print (keeping the same ratio). But you're likely chasing rabbits down the hole.
