probably needs an startShow(showType); when you press the button

  if (!isCycling && digitalRead(BTN_PIN) == LOW)  { // if button pressed, started cycling effects

    startShow(showType);
    isCycling = true;

  if (isCycling && (now - last_change > TIMER_MS)) { // go to next animation
    if (++showType > 4) {
      isCycling = false;
      ws2812fx.strip_off();
      ws2812fx.service();

that's intended. You press, it starts the animations and then terminates. A new press will start again.
