FWIW, I found a way to serve my own "curated" list of nodes from within my own node-red instance -- Here is the flow I'm using:

It starts with the /red/catalog.json http endpoint on the left, fetches the actual node-red catalog, then uses a JSONata expression to filter only the ones I want people to see. Then i added this to the editorTheme section of my settings.js file:
palette: {
catalogues: ['http://localhost:1880/red/catalog.json']
},
Of course, anyone can just change the filter to add whatever they want, so if real security is needed for your use case, then this would not be a good solution. But for our purposes, it serves to focus people on those nodes that we would expect them to use.
