Not all distros that exist in the current year are "modern". Mint for example, still ships with X11 and old forks of Gnome. Lots of people are running Arch with weird components that don't work well for whatever reason. And so on...
Modern means systemd, pipewire, Wayland, Gnome, an up to date kernel, etc... So the current Ubuntu and Fedora releases.
I've had 100% working laptops for 15 years now. Because I always run the newest Ubuntu.
I run Ubuntu and suspend is pretty much a nightmare to the point I just gave up pretending it exists. These are Dell computers sold with supposed Ubuntu support. Close the lid and put it in a backpack is inevitably an invitation for a hot laptop or empty battery when you pull it out a few hours later (for the record: Windows isn't any better at this in my experience so WSL never solved that problem either).
Previous laptops (all ThinkPads) used to be able to get everything all to work (debian) but it did take effort and finding the correct resources. Unfortunately all the old documentation about this stuff is pre-systemd and UFI and it's not exactly straightforward anymore.
Google "Dell suspend issues". It's just their computers, it doesn't work any better on Windows. My wife has had 2 Dell laptops now, neither suspended properly ever (and she only runs Windows). According to the internet, this is a Dell problem. One of her laptops also had the Wifi card break within 4 hours of use, brand new. But she likes the "design" and is stubborn.
Google harder. It's a general Windows problem. Microsoft can't even get it to work on their own Surface devices. Show me a Windows laptop that suspends properly and I'll show you a liar.
Well there you go. Meanwhile Linux suspend does work more often than not in my experience. I've had a ThinkPad, Acer and MSI laptop with working suspend on Linux.
Other than an up to date kernel, your list of what "modern" means is entirely wrong. The rest of the entries are polarizing freedesktop-isms. There's nothing out of date about, e.g., KDE Plasma.
I read all the links, most of the problems weren't bugs (Fan runs loud? Fans run under Windows as well... Only modern suspend? Literally created for Windows...). From all those links the only thing that was a bug was an issue with a kernel regression and 4/5 distros he listed weren't one I listed.
Maybe I was too positive on Fedora (I was going by it's reputation, I use Ubuntu for work). Ubuntu is solid.
Link 1: screen only updating every 2 seconds, visual glitches.
Link 2: brightness reset to full on screen unlock, fans turning on when charging.
Link 3: bluetooth troubles, speakers cant be muted if headphone jack is on mute.
Link 4: audio quality and low volume, wifi not coming back after sleeping.
Link 5: fans being too loud, poor sound quality.
Either your Stockholm syndrome is affecting your reading comprehension or you just take bugs like these as part of the normal "working perfectly" linux experience.
