[Google Pixel 6 Pro] foobar66:
I decided not to root my phone (yet) but still want to disable stuff which I never use (for example: wellbeing, live wallpapers, ...).

You certainly do not find the amount of "bloatware" on this phone that you find on the competition ... but anyway.

You can disable packages without root using "App Freezer" (https://play.google.com/store/apps/details?id=com.wakasoftware.appfreezer).

You have to read the instructions to enable it to work rootless-ly, but it does work (it uses device administrator permissions). Before granting that permission you must remove all accounts from the device (yes, even your Google account). Then activate the permission. Then reboot. Then add accounts again.

First install the app, then, once accounts are removed, do the following:

adb shell dpm set-device-owner com.wakasoftware.appfreezer/.receiver.DPMReceiver

Attached is an XML file (exported from App Freezer) with the packages that I have disabled.

Don't just blindly copy/paste this. Check and judge for yourself !!! There are probably packages which I don't use which you will want to keep !!!

My list of disabled packages (with very short description of what these APKs do).

App Freezer has ads. If you use an ad-blocker you will not see these. You can also buy the "pro" version from within the app (which I did to support the developer) - then ads are gone as well.

If you are rooted, then you can disable using (no need to use the "App Freezer" app).

adb shell pm disable <package-name>

I'll make a more detailed write-up of what these packages do when I have some more time ...
