I’m not familiar with MATE so I’m not sure what file manager they use. But, in GNOME, KDE Plasma, and XFCE file managers I’ve yet to use one that doesn’t have GUI file managers that are similar to, or much better, than a File Explorer from Windows.
Why not try it? If you use xfce from the default install your desktop is almost similar to windows, it should be pretty intuitive opening the file manager icon. Endeavour is is terminal centric, in that many things can be managed via terminal, which is much faster for certain things, but that doesn’t mean it won’t come with a file manager etc.
