Honestly I like Windows 11 better than Windows 10. I mean I don't like or use either one, but if I had to I'd go with 11 (with debloat script, Powertoys, WSL2 and blocking telemetry with DNS as much as possible)

This is subjective of course but I prefer both the visual and sound theme of Win11 (I despised Win10 in both regards). Plus it has some additional nice qol features like, I think, tabs in explorer?

You can get Steam on just about any distro, for years at this point. And there's always Flatpak for these cases too although for Steam I recommend native packages.

You're not wrong, it's definitely not something a n00b should attempt in most cases. But I've done this before to save myself the need for distrobox. A lot of proprietary software only offers .deb, but is usually either statically linked or comes with its own set of nearly all the libraries it needs. So just extracting and running it often does the trick on non-debian distros like Fedora in my case.

Seriously though, just use distrobox or see if there's an unofficial package for your distro that you trust (AUR/copr/ppa/OBS). It's more straight forward especially if you don't know what you're doing.

I'm not aware of another one. Some other distros like Ubuntu and OpenSUSE ship AppArmor instead, which does similar things but isn't considered quite as secure.

I know plenty of other popular distros don't ship any Mandatory Access Control system at all which seems like a very bad security practice to me. Same thing with Firewalls.

Facebook and Instagram, sure. But plenty of people are more or less forced to keep WhatsApp either because of people they want to be able to message that refuse to use anything else, or perhaps even because they need to be in some WhatsApp groups e. g. for work.

Communication platforms aren't like web browsers or operating systems where you can switch at will to whatever else works for you, you're more or less reliant on everyone you know also making the switch.

That'll work but distrobox is a much simpler solution

Also great when you get some software as a deb for old Ubuntu and don't want the trouble of manually making it work on a new system. Just make an old Ubuntu distrobox.

I don't think that would work since both GPUs are AMD and use the same driver

One thing you could do is plugging your monitor straight into the iGPU outputs and using DRI_PRIME only for applications that need the powerful dGPU.

Unless you want to run either everything or nothing on a specific GPU, I don't think there's a more convenient way than setting DRI_PRIME per application.

You listed AMDGPU-Pro as a kernel driver. Correct me if I'm wrong but I'm quite sure it is a proprietary userspace OpenGL/Vulkan driver that uses the open source AMDGPU kernel driver.

Try using XWayland video bridge. It should allow any XWayland apps to use screen sharing. Unfortunately most distros either don't ship it yet or ship broken versions but you can download nightly Flatpaks from Gitlab CI

Metro Exodus has a native version with decent performance
