Block sleep - OFF or else it won't sleep!
Usually the issue with sleep is that on waking up from sleep, it crashes. So you would turn block sleep ON if you wanted to stop it sleeping and crashing on wake. However, turning on Block sleep in BIOS will also disable sleep in Windows. Rather than that, use a Mac app like Amphetamine which works quite well.
I can't think of any other settings specifically. I did turn off CFG with the BIOS hack, but not sure if this helped or not. On my other Dell XPS, I didn't touch CFG and they all sleep fine.

If you are crashing on wake up, then I think hibernating -> wakeup would be the same as sleep -> wakeup. It's the wakeup process that causes a crash. In some laptops, it might be the NVMe drive causing it. Check the error when you reboot after the crash to see if you have any clues as to what causes the crash.

New Dell XPS 15 9500 System BIOS v.1.18.0 from 13 Sep 2022
Dell has released a new version of the BIOS which claims that "Fixed the issue where the system stops responding at the Dell logo while booting.". Will that fix the sleep/wake up issue in macOS?

make sure your USB ports are setup correctly, that could help with sleep/wake issues:
The New Beginner's Guide to USB Port Configuration
Important: January 2023 Update It's been a while since this guide was written and Apple has changed their USB sub-system in several significant ways. So please bear in mind: 1) From Big Sur 11.3 onwards the OpenCore XhciPortLimit Quirk stopped working. It hasn't been fixed yet. So generally we...
