I’ve carefully reviewed your post, and I may have overlooked the reasons why some believe you’re using Wayland, especially since you’re currently using i3. Anyway, I’ll talk about X11 ans Wayland options.
i3 is indeed capable of launching programs via keybindings and supports full mouse functionality. However, it does require significant configuration. To be frank, all tiling WMs necessitate customization. Additionally, many tiling WMs benefit from the installation of a separate tool to serve as a panel bar. Tiling WMs share the concept of shipping with a functional minimal configuration, allowing users to tailor their setup precisely to their preferences.
Here are - to my humble personal opinion - the “easiest” tiling WMs for X11:
- i3: you know it
- awesomewm: comes with a panel, menu, and widgets out of the box.
- bspwm: very lightweight and minimalist. Unlike others, it will require the use of sxhkd to define keybindings. The config is shell-script based, which may feel easier to some compared to lua. This was my preferred option before moving to Wayland and having tried awesomewm, i3, and dwm for years.
And for Wayland:
- sway: drop-in replacement for i3. It uses the same keybindings/config style as i3.
- niri: this one technically uses a “scrollable tiling” model (windows arranged in columns on an infinite strip) rather than the traditional tiling resizing. Due to this model approach, it could be intimated to you but it can achieve great things and may be just what you need for a 11" screen because you can have an infinite number of full/half screen windows that you can scroll horizontally or vertically (thanks to stackable windows and infinite workspaces number).
Talking only about tiling WMs I’ve used, but there may be great/better options out there. You can quickly check the list of features on their respective github page and watch videos to see what each of them can offer. Detailing all their features here would not be digestible.
Edit: except very few tiling WMs (I can think of two), they all fully support the mouse to click or move/resize windows.




Unless you have already made a decision and feel strong about Zathura, I’d like to mention Sioyek. It’s definitely an underrated pick for terminal PDF readers. It works just as well as Zathura, and can even go wayyyy beyond it.
