The first two OLED options are add-ons to the Core64. They allow you to display the current mode, voltages, or whatever else you come up with. Sometimes it's nice to have a hi-res display for troubleshooting, built-in into the device.
The last TFT option can be used to replace the LED Matrix. At the time of this writing, I do not have code written or active to make use of it. I've only tested that it works in the optional TFT LCD header socket rows. You could install the TFT flat on the Logic Board, replacing the LED Matrix. Or you could keep the LED Matrix, and use right-angle header pins on the TFT or a ribbon cable to mount the TFT as you see fit.
None of these are required to use Core64.
eBay options abound: 0.96" I2C IIC Serial 128x64 or 1.5" I2C 128x128 or similar I2C with SSD1309. Make sure you get one with the right chipset, and one that uses I2C, not SPI. Also make sure the power pins are on the left, and clock/data on the right. The Core64 Logic Board and LED Matrix allow the +/- pins to be either of the two on the left, as long as you configure them correctly with the nearby solder jumpers.
Sparkfun: 128x32 Blue OLED Teensy View made by Sparkfun with the SSD130, designed to stack on top of the Teensy. This option is one of the smallest, but it will increase the height of the overall Core64 board stack. It uses SPI and can be configured to work with the Core64. If you choose this option, you will not want to install the Core64 headers around the perimeter of the Teensy. Instead, you will want to purchase and install long pin female socket headers such as the Teensy Header Kit.
Here is a nice option from Adafruit.com using SPI, directly compatible with Core64:
Another VERY nice Adafruit option (SPI) that is directly compatible with Core64:
