I'm going some tech support for my brother today, and that's meant looking "under the hood" of his Windows 10 machine.
And it is astounding how poorly Windows handles indexing content.
I had to uninstall OneDrive and set it up again from scratch and in the course of that I moved the contents that had previously been synchronized to two folders with "(Old)" added to make sure that nothing got lost when we did it.
And I wasn't surprised when resetting his connections to his OneDrive store and the company Sharepoint store set off a flurry of indexing. I wasn't even surprised that that took a bit of time to finish; I was re- downloading a lot of files which from the perspective of Windows, all needed to be indexed anew.
What was completely surprising was that simply moving the those two "Old" folders immediately caused Windows to re-index that content! I decided to clean up the two separate "Old" stores into a single folder, and all of a sudden, the indexing which was at 0 in Settings:Search:Searching Windows
Windows isn't smart enough to recognize that these are all files that its already indexed and they're now just in a new location!
About 80,000 files were move about 30 minutes ago, and the re-indexing isn't even 25% done!
If I do a similar thing on macOS, it's done almost before the files have finished the move.
I'm really glad Alan does not know how badly the move to Modern Sleep has screwed up what was a perfectly good Windows feature. This goes back to at least 2020.

In addition, some Windows machine are only able to perform Modern Sleep. Mine was one until I found a registry hack to enable Hibernation.
But that's really no different than regular ACPI failures.
The "powercfg" utility, has some tools for collecting reports and
finding "hints" of a root cause.
In your example, since the machine is not entering a low power state,
I would be checking LastWake to see it bouncing out of the low power state.
The machine I'm typing on, draws 33W while idling in S0. Your example
is 27.5W in fake Modern Standby, which means it is fully in S0.
My machine includes a plugin video card (the inclusion of which
was forced by a bug in the design). The lowest S0 Idle I've got,
is a 6 core machine that runs idling at 22 watts (using its iGPU).
Then you have all possible combinations of broken and working stuff.

The theme repeats over and over again with modern computers.
Additional complexity, enlarged table of possibilities, and little
to show for all of it.
There is the potential (but not the guarantee) of a BIOS switch,
to aid in changing ACPI model.
And the worst case for laptops, is where the ACPI table has syntax
errors, the Linux parser points out the problem, the manufacturer
refuses (or is unable) to edit the BIOS and correct that part of it.
It's not always possible, when purchasing, to catch problems
like that before they sting you.
