Linux is not a company lol I hope that was a joke. Also Linux is not new.

Now to the software: it will likely run everywhere. Davinci resolve is a bit picky but also fine.

You have quite some Windows-only software. Check https://alternative-to.net or try running it through WINE with Bottles

To the Distro: this is complex. Many people will recommend Linux Mint and it is easy to use but very restricted. I dont think it is great really.

There are many many parallel efforts, so on Linux Distributions (Linux + packages + desktop + ...) you can get very different software.

For a painfree experience running Windows software and Davinci Resolve I recommend to try Bazzite

It is very different from others:

• it updates automatically in the background. But completely different from Windows. Updates always work and are efficient and stable. No 10 times rebooting
• updates finish and you can reboot any time to apply it. Literally a week later, nobody cares
• the reboot takes just as long as any other reboot, no downtime

The system is way better and more stable than "traditional" ones. This is quite complex but lets say while on Linux Mint, Ubuntu, Fedora etc. you will have an indivudual system, with individual packages and in the end some strange errors only happening on your setup, with Bazzite you will have exactly 1:1 the system that the developers create.

It is based on Fedora Atomic Desktops which are pretty great. But for your use case I dont recommend them.

I recommend the Bazzite Desktop version with the KDE Plasma desktop. This will be Windows-like in a very good way, but incredibly more efficient, faster and also more powerful. Like a Filemanager with tabs and extensions, that is not written in whatever bloat Microsoft uses (their Win11 stuff is so slow...).

To sum it up, on Linux you have to decide:

What Desktop environment?

• I recommend KDE Plasma a lot
• GNOME is also good but veery opinionated and minimalist
• I dont recommend others like Linux Mint's Cinnamon yet, as they dont support modern standards (Wayland)

What Distribution family?

• Debian, Fedora, Arch, OpenSUSE
• they are all a bit different but basically doing the same
• Ubuntu stems from Debian and became popular as "the beginner Linux" but they do very controversial stuff nobody else does (like the Snap store) and have tons of bugs. I used it a lot with bad experiences and dont recommend.
• Linux Mint and others also use Ubuntu or Debian under the hood
• Arch is very manual and difficult for new users, dont use it
• OpenSUSE does whatever they do, not recommended
• Fedora is pretty modern in their software, has a nice community and a big variety of options. They are not allowed to ship restricted media codecs for stuff like h264 video though
• uBlue (Bazzite, Bluefin, Aurora) is a project using Fedoras versions and adding nice stuff to it, making them usable out of the box. This is their goal, and they do it really well.
