Oops, this was in my Spam folder. It seems that this is the solution to the problem. Thanks a lot!

<div dir="auto">Check the random marker fill. I believe it's what you are looking for. As you can see in the docs, you can decide how many points you want to insert inside the polygon. This option can be derived of each feature attributes </div>

<div dir="ltr">This may not be an answer to your question, but the Density Analysis plugin (<a href="https://plugins.qgis.org/plugins/densityanalysis/" rel="noreferrer noreferrer" target="_blank">https://plugins.qgis.org/plugins/densityanalysis/</a>) will create
a uniform set of polygons over an area of interest with a NUMPOINTS attribute of the number of points are contained within the polygon. The NUMPOINTS value can be weighted using some other attribute. It will automatically style the density map as well from
a given color ramp.

<div>I have a similar research problem, and the dots seem to be a wonderful solution. </div>

Given that your polygons should generate a uniform density of dots within the area they bound, I don't see value in generating the dots for symbology.</div>

<div>The polygon area may vary, as it does in my research (distribution of burials in administrative areas). Therefore, a small area always looks underrepresented as compared to a larger area, and vice versa. I have large administrative areas with low densitiy,
but they look well populated even with a very light shade of grey. </div>
<div><br>
</div>
<div>So I would like to try to find a solution to Chris' problem since the representation with dots is closer to reality than colouring areas. I will report when I found a solution for my use case -- though this may be autumn...</div>
