Do they mention CarPlay? It drives me crazy that it only integrates notifications with Apple first party apps. It will send me notifications for iMessage or Apple calendar, but completely silences and hides Facebook Messenger, WhatsApp, Google calendar, Google voice, etc no matter what settings I try. It's frankly dangerous because it forces me to check my phone while driving in case of an urgent message or call. Meanwhile Android auto will show me all notifications and I can silence them while driving if I choose.

CarPlay supports notifications with non-first party apps like Microsoft Teams. I don't use everything on your list, but WhatsApp definitely supports CarPlay notifications. You may have them muted. You can mute/unmute on a per-app basis -- go to the app settings and adjust the "Show in CarPlay" toggle.

I haven’t used WhatsApp for while so maybe I’m wrong about that one, but Messenger definitely doesn’t work. I wish it was opt in by default for all notifications, it’s annoying so many don’t work.
