>knowing that Netflix, YouTube, and even older emulators only work in 16:9 or 4:3 disgusts me.
Ultrawide content exists on YouTube and Twitch. A lot of movies are shot in ultrawide, but are adjusted for 16:9 screens. I know I've seen movie that was properly adjusted for my ultrawide monitor, but I forget what movie and on what service. In any case, consider pirating movies for a premium experience. If a movie is shot in ultrawide, it will be shown in ultrawide. As for emulators, I know some emulated games can be modded to be ultrawide, but your mileage may vary. In any case, there are a ton of games that are being decompiled/recompiled to run natively on PC, and these games do support ultrawide, such as: Ocarina of Time, Majoras Mask, Starfox 64, Mario Kart 64, Sonic Unleashed, Link's Awakening, Bloodborne, etc.
> I find it ugly to have black bars.

I did too, but I grew out of it because of my phone. Modern phones are basically "ultrawide lite". A large portion of my media consumption is on mobile and I got used to the empty space. When ultrawide content does appear, it's a neat and very appreciated treat. Consider an OLED ultrawide. Might help. If you tend to multi-task, an ultrawide is so fucking nice to have much more space when you have windows side by side.

>Okay, for some recent games like Call of Duty or Forza, playing in 21:9 is beautiful, but most of the time, it's not optimized. Even Elden Ring doesn't work in 21:9.
A lot of modern games support 21:9 now, to the point where it's becoming expected. While there are still a lot that don't, I'd say the gap is getting smaller and smaller. There are a ton of unsupported games that can be modded to support ultrawide, like Elden Ring.

Overall, the benefits of an ultrawide vastly outweigh the downsides. Games are a fucking marvel to behold in 21:9 and I'll never use a 16:9 as a main monitor again. Even though 3DS games aren't ultrawide, they fit the screen beautifully with this layout
