Everything everybody else said but also for a noob user, the window manager matters a lot. It’s the part of the OS that renders the graphical user interface (GUI - menus and title bars and everything). Some are super basic (and often very lightweight / snappy). But KDE (super SUPER configurable) has a button for EVERYTHING. And because it’s so configurable I almost guarantee someone’s made a configuration that mimics widows aesthetics and interface, and that might make things a little easier for you until you’re ready to dive in a little deeper. And KDE used to be way too intensive for most computers but most modern ones can run it easily.
