I like XFCE a lot. It's really great especially if you're one who uses the browser for a lot of stuff, and don't care about Wayland.

I install arch from scratch. Arc dark gtk theme. XFCE. I just delete the dock and make the menu the inbuilt whisker menu so it looks like the windows ui which I am comfy with. Add key bindings for win+numpad for window snapping, add super key binding for start menu. Looks nice, very very fast.

None of it's inbuilt apps tho. I use the browser to open basically every file. The Google docs extension handles office files. Pdf, images, are opened natively obviously. VLC for media.
