Make sure you haven't accidentally unset DISPLAY after it was set by
Sway and make sure DISPLAY was inherited by terminal emulator, shell and
whatever invokes those (e.g., tmux/screen, wofi/dmenu-wayland).

CONSOLEKIT option in x11-toolkits/wlroots requires https://reviews.freebsd.org/D18754
Please, wait until you're comfortable with Sway before enabling the option.

Sway itself uses OpenGL acceleration. To see what clients use try mpv e.g.,

  $ mpv --msg-level=vo/gpu=v --gpu-context=wayland /path/to/file.mp4 | fgrep GL_
  $ mpv --msg-level=vo/gpu=v --gpu-context=x11egl /path/to/file.mp4 | fgrep GL_

Did you disable X11 option in x11-wm/sway or x11-toolkits/wlroots?
It seems your debug log lacks something like the following:
