How to define a singleton page in Studio v3. Can anybody point me to an example?

Granted it's been a minute since I ported my test studio over, but you would define the Structure in the same way as you would for V2.
Then, to control deletion/duplication/creation of new documents you'd add something like the following to your config:

document: {
      newDocumentOptions: (prev, context) =>
        prev.filter(document => !singleEdits.includes(document.templateId)),
      actions: (prev, { schemaType }) => {
        if (singleEdits.includes(schemaType)) {
          return prev.filter(prevAction => prevAction.action == 'publish');
        }
        return prev;
      },
    },
Note that my 
singleEdits
is an array of document types.

Could you show me the config file so I see this in context?

Yep!
export default createConfig([
  {
    name: 'default',
    title: 'studioDaddy',
    projectId: 'k8p6uw8a',
    dataset: 'development',
    basePath: '/',
    plugins: [
      deskTool({
        name: 'sandbox',
        title: 'Sanbox',
        icon: MdOutlineBugReport,
        structure: sandbox,
      }),
    ],
    tools: [],
    schema: {
      types: schemaTypes,
      templates: [],
    },
    document: {
      newDocumentOptions: (prev, context) =>
        prev.filter(document => !singleEdits.includes(document.templateId)),
      actions: (prev, { schemaType }) => {
        if (singleEdits.includes(schemaType)) {
          return prev.filter(prevAction => prevAction.action == 'publish');
        }
        return prev;
      },
    },
  },
]);

As you probably noted, I am a total Sanity noobie 😉 I have this config file now but it does not change the 
siteSettings
and 
navigation
content types into Singletons. I can still create more copies. Any idea why?
import {defineConfig} from 'sanity'
import {deskTool} from 'sanity/desk'
import {schemaTypes} from './schemas'

const singleEdits = [
  { type: 'siteSettings' },
  { type: 'navigations' },
] 

export default defineConfig({
  name: 'default',
  title: 'ruhrpott-studio',
  projectId: '349a1vg2',
  dataset: 'production',
  plugins: [deskTool()],
  schema: {
    types: schemaTypes,
  },
  document: {
    newDocumentOptions: (prev, context) =>
      prev.filter(document => !singleEdits.includes(document.templateId)),
    actions: (prev, { schemaType }) => {
      if (singleEdits.includes(schemaType)) {
        return prev.filter(prevAction => prevAction.action == 'publish');
      }
      return prev;
    },
  },
});
