This might be obvious but it wasn't for me, so I'll leave it here in case anyone else encounters the same problem;
The code shown in this specific example doesn't immediately work for me. Not sure why, but it seems like home-manager doesn't pick up on the specified specialArgs. I could get it to work by using home-manager.extraSpecialArgs instead.
For reference, this is my flake.nix

{
  description = "Main NixOS flake";

  inputs = {
    # NixOS official package source, using the nixos-23.11 branch here
    nixpkgs.url = "github:NixOS/nixpkgs/nixos-23.11";
    nixpkgs-unstable.url = "github:NixOS/nixpkgs/nixos-unstable";
    nixos-hardware.url = "github:NixOS/nixos-hardware/master";
    home-manager = {
      url = "github:nix-community/home-manager/release-23.11";
      inputs.nixpkgs.follows = "nixpkgs";
    };
    # fw-fanctrl.url = "github:mdvmeijer/fw-fanctrl-nix";
  };

  outputs = inputs@{ 
    self, 
    nixpkgs, 
    nixpkgs-unstable, 
    nixos-hardware, 
    home-manager, 
    ...
  }: {
    nixosConfigurations.<hostname> = nixpkgs.lib.nixosSystem rec {
      system = "x86_64-linux";
  
      modules = [
        # Hardware definition from https://github.com/NixOS/nixos-hardware/blob/master/flake.nix
        nixos-hardware.nixosModules.framework-12th-gen-intel
        ./default.nix

        home-manager.nixosModules.home-manager
        {
          home-manager.useGlobalPkgs = true;
          home-manager.useUserPackages = true;

          home-manager.users.<user> = import ./users/<user>/home.nix;

          home-manager.extraSpecialArgs = {
            pkgs-unstable = import nixpkgs-unstable {
              inherit system;
              config.allowUnfree = true;
            };
          };
        }
      ];
    };
  };
}
