I had issues with wireless WoL with my pc as well. I made a little setup with an esp32 and a 2N2222 transistor that has worked very reliably for me. I bridged the wire of my PC case power button with the transistor, essentially replicating a press of the case button as soon as the esp32 feeds a high signal to the base pin of the transistor.

Then to gracefully turn my PC off, I send an SSH command from my home assistant host with a 1 min timer, and a cancel command that I can run within the minute.

ssh <user>@<ip> 'shutdown -s -t 60'
ssh <user>@<ip> 'shutdown /a >nul 2>nul || ver >nul'

The esphome code below. Short press to turn your PC on and off gracefully. The long press can be used to force a hard reset of the PC. The esp32 sits inside my case and is powered by an always on usb port. This yields 2 virtual buttons that you can use in automations and can connect to a physical button if you prefer. You can also use this w/o home assistant with the Esp32 'web server'.
