Transitioning to CWM

I mostly just use a terminal and Abrowser these days. I'd like to transition from MATE to CWM (package "openbsd-cwm").

Things I need:

* Wi-Fi applet
* battery indicator
* volume control
* clock
* MATE lock screen (switch user)
* IBus input methods
* Compose key on Caps Lock

What packages should I use? I know the package "polybar" can accomplish a lot of this, but I'm not familiar with its configuration.

I notice xterm treats the Alt key as a Compose key. There is no way to get it to act like actual Alt.

Ideally I would like to use Hikari (CWM-inspired Wayland compositor) or Sway, but I know that won't work well with LightDM, Trisquel's session manager, and I'd like to keep Trisquel's session management entirely intact, including on lock screen. User switching is very important to me.
