I’d recommend sway and waybar. Waybar offers some cool customizable templates. Currently I also use bemenu as a launcher and dunst/poweralertd for notifications. I make heavy use of stacked or tabbed layout during general use.

sway has pretty decent mouse support, but for optimal productivity try to get used to the keyboard shortcuts. As soon as moving/resizing windows and changing desktops becomes muscle memory it’s a whole different ball game.
