All manual sleep triggers cause pc to immediately wake but auto sleep functions (mostly) correct
I'm having a hard time figuring out why this is happening. If I wait for my pc to sleep automatically (see settings below) then things function as expected (screen turns off, pc lights/fans turn off, pressing any key wakes the pc). But if I press my power button to sleep the pc, go to the start menu and press sleep, or run systemctl suspend the computer will enter sleep for like 2 seconds and then just wake up on it's own. I don't even know where to start diagnosing what is going on since sleep does work but only when it kicks in automatically.
EDIT: Also the reason for the "(mostly) correct" in the title is one time my pc automatically entered sleep mode (screen turned off) but my pc lights were on and my fans were running at full speed. It seemed to be a one time fluke and I didn't have anything unusal open.

Solution
Okay the last comment on that reddit thread was my issue. I narrowed it down to my wireless logitech G502 X mouse causing my pc to wake 1-2 seconds after going to sleep. My best guess as to why the mouse wasn't doing this when the computer went to sleep naturally is that the mouse/usb dongle were going into a low power state after not being used for awhile. I also have an old wired logitech keyboard (like very old, weird eyeball logitech logo old) but thankfully that was not causing my pc to wake. After doing the below changes I can sleep my pc manually and it does NOT wake up 1-2 seconds later on its own. The downside is I can't move my mouse to wake my pc but thats not a big deal for me since I can just tap a key on my keyboard and it wakes.
A very similar (but technically separate) issue can occur if you have a gigabyte motherboard, in which case use the fix that Cilantro linked in their message below this one.
