I went into void as my first DIY distro, mainly because I wanted to mess around with window managers and it was a very good experience. Runit made my underpowered laptop boot into linux in like 4 seconds, crazy fast. XBPS package manager was always really really fast too. I like the fact that nearly everything you need is in the official repo, instead of having to delve into the depths of something like the AUR. I also managed to make a contribution to the repos with the help of the community on the IRC chat rooms which were very noob friendly. Overall just a solid experience.

When an app supports linux, it can do so by either:

• packaging it for popular distro repositories,
• giving instructions on how to build the app from the source code

or

• package it on distro-agnostic, package management solutions like flatpak or appImage.

These last ones are sandboxed environments. That means they have their own dependencies isolated from your system, so they dont have to deal with every distros pecularities at the cost of using more storage space. This is very useful for developers and in your case benefitial for you because you can have both steam and zoom via flatpak on mint, arch or any obscure distro that has flatpak available, without any problems.
