It's not as hard as it seems.

I should have just used AI lol
I totally thought it was gonna be Greg Abbott but with tank treads instead of a wheelchair
Bazzite, it's an immutable Fedora-based distro, so in the unlikely event that it breaks, you can just revert back to whatever you had before.
Nobara is similar, Fedora-based but not immutable, which means you can tinker with it, but possibly also break it. Made by Glorious Eggroll, the guy behind the GE versions of proton and wine.
Mint is a more general-purpose distro, based on Ubuntu (which itself is based on Debian), but it's very user-friendly and does just fine with games.
Manjaro is fine, it's the one I put on my mom's computer because she needed a Windows program that I found in the AUR. It was pretty decent for the four games that she plays lol (The Sims 4, AoE2, Neverwinter Nights, and Prince of Qin). It's Arch-based, but not bleeding-edge like Arch, so it's ostensibly more stable.
As far as the Index goes, idk about that, as I don't own one. However, I just DDG'd "valve index on linux", and quite a few guides came up, so it shouldn't be too hard to get it going. Plus Valve is a pretty Linux-friendly company,
I like the Arch wiki's version: Reboot Even If System Utterly Broken.
Lmao, that thumbnail
Ventoy is a tool specifically for booting from USB drives.
I also choose this guy's dead soul
Like RDP? Or are we talking like, some sort of ssh GUI, where you just wanna access the files on the Windows machine? Most file explorers on Linux do that natively. Or are you talking about compatibility with .exe files? If so, there's Wine and Proton, but those could need some configuration.
Unfortunately, if you're managing one computer from another computer, you're going to be aware of it regardless of which OS you decide to use.
Q4OS has an installer like that, but you have to change the boot order after installation, I don't think it uses grub.
