@KragwulfI was VERY unhappy with Windows, but I stuck with it because Linux was this big scary monster to me and I didn’t have the energy/willpower to try and learn it.
It took three days.

You really want your butt kicked? Install FreeBSD 
I’ve spent literally years trying to perfect my Arch Linux install. Just recently figured out how to get Xorg working properly with my setup and with dynamic GPU binding. It’s still not perfect, as the display goes to sleep the input gets switched to HDMI, which then displays a black screen and I have to manually switch it back to display port.
The more specific your use case is, the more you need to tinker with your system.
We have COOKIES!!!
If it’s not enough, you can try Gentoo or better, Linux From Scratch. 
I’ve kept an old PC around to “tinker” with different distos. If you have access to something like that, try installing vanilla Arch just by following their directions and not using the install tools (the “Arch Way”, as they like to call it.). It will provide a challenge and have the added benefit of helping you gain familiarity with what’s underpinning EndeavourOS.
…these days, that “Old PC” is just running vanilla Debian. Partially because my son has a need to get familiar with it for his work. If he borks my PC, no harm done and he “learns by doing”.
Time to take up ‘Freebsd’ if you’re bored. . . . that was supposed to be an easy distro 25 years ago for an accomplished computer enthusiast. That’s what the author of a book that came with the software said. . . It was anything but easy. . … . Some people think something is easy until they try it. Linux 30 years ago wasn’t the Linux as it is today in many ways. Yes it’s gotten real easy now to do a lot of things with Linux. Thirty years ago that wasn’t the case.
Installing EOS is easy, running games with Steam from Steam is also trivial, but there are dangers here, because maintaining the system can be quirky & it’s very easy to bork up things if the customization bug bites you. I hope you are on BTRFS, then you are probably set for a long time. 
This is doubly true, since you are using Nvidia. Long time happiness is not guaranteed without a good rollback option. I used to feel dread whenever Nvidia driver updates popped up.
Why did you leave Linux Mint? Was it causing issues?
Install NixOS in a VM. That will keep you busy. You’ll have reliable EndeavourOS to run on top of.
Yes it’s so annoying when everything works…
I just didn’t like Cinnamon, honestly. I went looking into KDE distros and that lead me down the Arch rabbit hole. Ended up with Endeavour because it was what a friend recommended for me.
What??? I’ll have to investigate this myself. My current “want” (that i haven’t looked at on Xfce) is the “Win+left/right/up/down” snaps
Kragwulf, this post is brilliant.
I’m currently building on AMD in order to replace a rather aging system on Intel 8700K and Radeon-7, had decided that this is the end of my Windows gaming PC because I don’t fancy co-pilot and whatnot other things where the OS tries to operate me.
I considered this a big, scary thing to do and we might share similar experiences around Mint (but that was 10 years ago for me)
Your summary has taken a LOT of worry off my heart, thanks for sharing your “frustration”
Sorry for your convenience. Wan’t a

That was actually my story with Mint.
But since I’m no gamer and I was unhappy with Plasma as I tested it during my first-distro-research period, I decided to stick to Mint for a year.
