Photo management can probably be accomplished with GIMP (or even simpler tools, depending upon what you want to actually do). Video is a struggle and a big reason I'm still on windows. Davinci resolve technically works on Linux, but it is fiddly as hell. I got it working on Mint, upgraded Mint and just gave up in frustration a couple hours in to trying to get it to work again.

Check out ubuntu studio - https://ubuntustudio.org/

You can install all the same apps on any distro so in the end it won't matter too much which you choose as long as it's a mainstream one.

Tuxedo is probably great, it is Ubuntu based and EU based. But if you want something different try fedora, that’s what I’m using and having a great time despite being close to tech illiterate.

You should choose a distro where you don't have to do a lot by yourself, since you are new. Another Point is software availability. Since it seems you want to use some specific software, check if its available as a flatpak (in which case the distro doesn't matter as long as the distro supports flatpak), or if it is directly available in the packages of the distro.

For concrete recommendations: as lembot_0004 said, debian and ubuntu are good general purpose starting points, but since ubunti updates some stuff a bit faste than debian and has a 3rd party driver installer, you might want to choose it if you have the need for it (for example if the current debian version does not support your graphics card yet).

I personally use linux mint, which looks more like windows on the desktop than debian or ubuntu.

Other people here have also recommended fedora, so if you want, you can check it out too.

Ah, you've made your first mistake. You asked the Linux community a question. Welcome, it kinda sucks here.

Anyway, you had the right idea. Everybody has different answers to the distro question because it has less to do with the distro and more luck of the draw that some combination of distro-specific customizations and personal choices picks up your hardware without much issue first try.

The real way to guarantee that outcome (as much as possible in the Linux ecosystem) is to buy hardware that is specifically tied to a specific distro. Tuxedo is a way to get there. Once it's all up and running that choice will be mostly irrelevant. Your choice of package management and desktop environment may have a bigger impact instead. Just go with a solution that comes preinstalled or you can verify will work out of the box.

The software part is probably fine in most entry point distros that aren't too uppity about FOSS-only and don't make you go through hoops for third party repositories. I haven't owned a Tux, but I presume that includes them, considering their positioning. If it's being recommended for novices or it comes preinstalled it's a fair chance it's all gonna be in there without having to spend too long in search engines.

Debian or Ubuntu. 1st if you have some basic self-respect, latter if you're a corporation boot-licker.

All other distros are for those who know exactly what they want and why. And for kids who want to look like hackers from movies.
