Finding library for LCD

I am planning an exploration of using
2.7" OLED 12864 display module SKU: FIT0328
and need a library file. The tutorial page code starts with #include <LiquidCrystal.h>. In the Arduino IDE libraries I find the library LiquidCrystal_PCF8574.

Is that the one to use?

There's an Arduino library link on the bottom of that page. Why not use that one?

That library is u8glib. According to the official page for that library: https://github.com/olikraus/u8glib

Note: There will be no more development for U8glib. Please use u8g2.

So it might be a good idea to use u8glib2 instead to benefit from recent development work.

Thanks pert
