QubesOS – A reasonably secure operating system
I've been using Qubes for the past 2 years while going to school, and I found it really fun and helpful. A lot of professors had me download random closed source software from random websites during the pandemic, and it was easier to download it to a VM than to convince them about Free Software. More than that though it's been really helpful just for my own workflow. I can hit a keybind and start working from essentially a fresh linux install. It's easier to stay on task when each VM is designed to only do one kind of task. It's also nice having debian, fedora, windows, kali, and whonix all easily accessible on the same machine.
The main sticking point for me is that Qubes is reasonably secure from _myself_. I make mistakes. I first started using linux with an Ubuntu install that I broke a year later because I accidentally added in a space when typing `rm -rf ~/Arduino` which made it `rm -rf ~ /Arduino`. On Qubes I can `sudo rm -rf /` on the VM I'm using right now and not break a sweat. I have a keybind to spawn a disposable "airgapped" VM to deal with sensitive or untrusted data, and it helps knowing that even if I mess up with whatever I'm doing, the VM will keep everything reasonably contained.
Some cool things that Qubes has outside of just VMs are its features enabled by the communication between VMs. Notable ones are Split GPG (https://www.qubes-os.org/doc/split-gpg/) which let you use a VM as if it were a smartcard for GPG and Split SSH (https://github.com/Qubes-Community/Contents/blob/master/docs...) which let you isolate your private SSH keys from your VM running your SSH client.
There are some sticking points around Qubes. For instance, I use Tailscale to connect my computers to each other from anywhere. Tailscale's install scripts add their keys to my VM's package manager for updates and installs. The proper way to do this in Qubes is to clone a TemplateVM, run Tailscale's install script, update, install, and then base an AppVM off of it. But that creates an entire new OS taking up storage and requiring updates. You can hack a way around this in an AppVM which saves a considerable amount of space, but it takes a lot of upfront time to do and requires you to manually update it.
Another sticking point is hardware acceleration. The desktop environment has access to hardware acceleration, so it runs fine, but opening videos in AppVMs is all software decoded. I'm on a Thinkpad T580 and it can run 1080p videos, but the fans turn on and can't do 4K. When I want to game or do something GPU heavy I either stream from my tower or completely switch over.
Overall, I'm really happy with Qubes and I'm planning to stick with it on my laptops.

GPU passthrough on Qubes?
I can't speak to 17+ GPUs - but have successfully passed through a single high-end GPU for gaming via following these instructions: https://github.com/Qubes-Community/Contents/blob/master/docs/customization/gaming-hvm.md
- Qubes OS new templates?
- Installer crashes at last moment ?
- Dual-booting Qubes and a Debian distro?
- ArchQubes?

Windows 7, 10, or 11 vm in Qubes-Os
Yes its possible. But check here under "Audio Support", also says at the bottom that windows 7, 10 & 11 are fully supported. As for how to install Windows, here. And installing Windows 11 by disabling the TPM check: https://forum.qubes-os.org/t/windows-11-in-qubes/6759/8.

Bubblewrap – Low-level unprivileged sandboxing tool used by Flatpak
Also of interest is https://github.com/igo95862/bubblejail , a less low level program on top of bubblewrap.

You could probably use Firejail or Bubblejail for this.

Breaking all macOS security layers with a single vulnerability
Please do not use firejail. See this issue page: https://gitlab.alpinelinux.org/alpine/aports/-/issues/12635
Bubblejail is an acceptable alternative https://github.com/igo95862/bubblejail
