For LCD/TFT screens of that size, besides the Nextion models, I have only found displays based on the SSD1963 controller (800x480 pixels), and that's not (yet) supported by ESPEasy.

For getting MQTT values on ESPEasy, you can use the MQTT Import plugin. Depending on the build used, not all options like filtering and mapping, might be available though.

You can use a Nextion Enhanced HMI Intelligent Smart USART Serial Touch TFT LCD Module. You can also use an E-Ink (electronic ink) display.

Since you're facing issues with MQQT, you can take a look at this write-up:

It discusses broadly about the MQTT protocol. It features ESP32.

That's not what's said, OP just asked how to get values from MQTT on ESPEasy, that's what the MQTT Import plugin is for.

Your link is dead (404), but the HiveMQ site has a very elaborate description of the MQTT protocol.
