LoveWindowsAgain VS WindowsSpyBlocker

Use LoveWindowsAgain from GitHub to easily uninstall all bloatware + some other neat tweaks. It's also extremely easy to use.

I have used this a few times without issues to disable telemetry/tracking/bloat. The dev also has a tool for Win10 users called Privatezilla, just throwing that out there in case anyone on W10 is reading this..

LoveWindowsAgain

I would only feel comfortable suggesting Privatezilla because it is open source. With OO ShutUp10++ you are installing software that tampers with your system and there is no way to understand how it works or if it's doing anything malicious. Privatezilla is also still maintained, as a matter of fact, they just released a big update code named Pollux that integrates LoveWindowsAgain which is a Windows 11 utility to disable various stupid things in Windows 11. I would also recommend what u/domsch1988 suggested, and use winget to uninstall anything else you don't 100% need.

Or by using an open source tool like ThisIsW11 or LoveWindowsAgain

Windows Spy Blocker = This will add a bunch of Windows IP addresses to your Windows Firewall. The basic settings should not impede functionality. It should also allow you to switch ntp (how Windows sets it's Clock) to more open alternatives.

Telemetry is similar to Windows 10. However, you can stop most or all of this with the hosts file or a Pihole. Add this: https://github.com/crazy-max/WindowsSpyBlocker/tree/master/data/hosts

You can use WindowsSpyBlocker on Windows to change the NCSI, or you can change it yourself

Also, the New Oil recommends WindowsSpyBlocker so that may be another option for you.
