Well, I settled on a KaOS, a singularly KDE-focused distro, because it looks good, works fast, is simple, and has what I need for now. I found it interesting how the developers optimized the distro to work with only KDE rather than overextend with too many desktop environments.
I was going to start out with the Manjaro KDE, but the live USB wouldn't boot on my computer. I could try Manjaro with some other DE, but I feel the most comfortable with KDE starting out. These windows managers seem interesting, too.
As my Linux experience progresses, I'll try out other distros and maybe switch to a different distro, but KaOS seems like it will allow me to get things done out-of-the-box and mess around with other distros, with my current limited free time.
