Fedora Kinoite, because it fits my workflow the best and has a nice mixture of stable and leading edge.
Everything I run was containerized either way (Flatpak, Docker or Podman) long before I switched to an immutable distro.
I have lots of different development environments for various versions of different programming languages that are incredibly easy to setup, throw away and recreate with toolbox without having to dive into the language specific tools for creating virtual environments (venv, conda, ...). On regular Linux/Windows systems I end up at a point after a few years where there is junk laying around everywhere from 6 different PHP versions, 7 gcc variants and 8 .NET versions.
I was on Fedora KDE before that and the main reason for choosing it was that Ubuntu/Debian/Mint were too old to include firmware for my GPU. Arch and derivatives are on the opposite side of the spectrum and are too new for my taste, I'm fine with waiting a few weeks for .1 versions to release with bugfixes.
As for why not Bazzite or Aurora: Because I wanted to be as close to the original (Fedora & KDE) as possible. The modifications those distros make (and I need), I can do myself in a few minutes.
I do recommend Bazzite or Aurora for less experienced people though, they have a lot of tweaks that Kinoite is really lacking. Kinoite, just like the Fedora KDE variant has a lot of polishing issues that quickly become gigantic obstacles for beginners (Nvidia drivers, Flathub repository, H264/H265 codecs, missing udev rules, ...)
Steam automatically uses the native version if one is available, unless you override the compatibility tool to be Proton instead of the Linux runtime on a per-game basis. Nothing changed in that regard.
If you want to actually digitally sign you can add a key in your OS and then go to "Tools -> Digitally sign" where you can choose a background image which you then can drag where you want to have it.
If you only want your written signature in there, you can create a stamp for it. Click on the arrow beside "Yellow Highlighter" (or whichever tool you have selected) in the top right corner. Select "Configure Annotations" and hit "Add...".
Make the type a stamp, give it a name like "Signature" and select an image you want to use. After that save and apply.
You can now select your stamp in the top right corner and place it anywhere by clicking or dragging over the PDF.
As a side note, depending on where you live a written signature in a PDF is meaningless at least in terms of legally binding documents.
