Debian で non-free-firmware というコンポーネントが増えることになり，実際に移動し始めたとのことで利用できるように設定しました．
/etc/apt/sources.list を編集します．直に編集することも出来ますが， apt edit-sources を使うと保存時に文法チェックをしてくれるのでおすすめです．
$ sudo apt edit-source

早速 non-free-firmware から firmware-iwlwifi が降ってきました．

今回 bookworm(testing) で設定しましたが，sid(unstable) の場合も同様だと思います．
環境
$ lsb_release -a Distributor ID: Debian Description: Debian GNU/Linux bookworm/sid Release: n/a Codename: bookworm $ dpkg-query -W apt dpkg apt 2.5.5 dpkg 1.21.19 $ arch x86_64
追記) Bookworm 新規インストールの場合
non-free-firmware が有効になった Debian-Installer Bookworm Alpha 2 が出たので少し試してみました．
パッケージマネージャの設定で，「non-free のファームウェアを使用しますか?」で「はい」を選択することで， source.list に non-free-firmware が設定されるのを確認しました．
