You'd probably like ThisIsWin11 & TweakUIX then, though you've already got a good handle on this stuff.

ThisIsWin11...
ThisIsWin11 lets you customize Windows 11 all in one place. It is slowly expanded as a practical all-rounder for Windows 11 replacing some discontinued PowerToys components and adding additional ones.
Included components
GetStarted ThisIsWin11 is starting off with a helpful introduction to what you can find in Windows 11. This component extends Microsoft's Get Started app.
OpenTweaks allows it to customize the more obscure settings of Windows 11 system's UI. It replaces Microsoft PowerToys TweakUI (available from Windows 95 - Windows XP) which was no longer integrated into the relaunched PowerToys as of Windows 10.
PumpedApp makes it possible to remove unwanted features and apps from Windows 11 such as the Camera and Alarm apps, and other preinstalled bloat that you can live without.
Packages powered by Windows Package Manager allows you to create your own custom install packages.
PowerUI allows you applying automation capabilities based on PowerShell and community scripts.
Extensions allows you creating custom tweaks
TweakUIX...
This will be my first attempt to recreate a part of the classic at that time ubiquitous Tweak UI app featuring the classic look.
ThisIsWin11 was my first attempt to enhance somehow the PowerToys productivity apps with some system tools. It was partly based on tweaks of the TweakUIX mentioned here. Somehow I prefer this standalone version more, so I decided to push it to public on Github. My private version had all other tweaks integrated, so the code base including all tweaks of this app was largely taken from the last stable version of the TIW11 OpenTweaks module.There is still a lot to do and a lot of spaghetti code to clean up, but the first step is done..
...and yes, this version also brings some advantage over TIW11. The stone-age ui requires less resources and of course flickers a bit smoother on the screen and runs at time of writing also on Win10.
