Answer 1

var result = myDbContext.Listings
   .Where(listing => ...)                   // only if you don't want all listings
   .Select(listing => new
   {
        Id = listing.Id,
        Name = list.Name,

        Categories = listing.Categories
            .Where(category => category.Enabled) // keep only the enabled categories
            .Select(category => new
            {
                Id = category.Id,
                Name = category.Name,
                ...
            })
            .ToList(),
       })
    // this will give you also the Listings that have only disabled categories,
    // so listings that have any categories left. If you don't want them:
    .Where(listing => listing.Categories.Any());
