I couldn't find record of the new bundle identifiers posted anywhere so I thought I'd share my findings for anyone who may need these for hiding some of the new built-in apps via the "Do Not Allow Some Apps" restriction or with the "Home Screen Layout" payload. They don't currently auto-populate in Jamf Pro when typing the app name, so just paste the new bundle ID in, save the line entry for the app, and click edit again and you will be able to add the app name.

Ran into a problem with restricting apps on a device for a student who needed the accessibility feature "magnifier"...it was blocking all access to it if set to only allow specific apps...normally all a11y features still function. I searched everywhere trying to find a Bundle ID and nothing including the apple support site's list. Hour on the phone with Apple support and using console to try digging up this unlisted bundle id and success! Hoping he gets Apple to actually list it on their end as well but figured I would post it here as well.
If needing to use the magnifier feature located in accessibility, the Bundle ID for that "app" is:
In Jamf, adding it doesn't actually find it so you need to enter it in the first field and then again in the actual bundle field.
If you haven't tried the magnifier feature, you should check it out...extremely useful now that device cameras are getting so good.
com.apple.news should work to hide/restrict the News app itself, but the widget is restricted by a separate item in the Restrictions payload, from what I've seen in past testing. Try adding this to your configuration profile and see if that helps: Restrictions > Apps > News (Include + Restrict)
