This has been flashed with

VERSION: "2v04",
  GIT_COMMIT: "3956264e",
  BOARD: "ESP8266_4MB",
  FLASH: 0, RAM: 81920,
  SERIAL: "dc4f227e-3bcd",
  CONSOLE: "Telnet",
  MODULES: "Flash,Storage,hea" ... "r,crypto,neopixel",
  EXPTR: 1073643636

Able to connect and set up Wifi using:

screen /dev/tty.wchusbserial1460 115200

as well as "nc" over Wifi:

nc 192.168.0.19 23

However, on a Mac Mojave Chrome, the serial connection does not show (baud rate changed to 115200):

Also can't connect via Wifi.

Is there a Chrome setting I'm missing?

I won't mind pasting code using "screen" however I don't know how to include "require"d modules if not already included.

Based on the error message No navigator.serial - Web Serial not enabled I guess you are not using the "installed" chrome app. Try to install it: https://chrome.google.com/webstore/detail/espruino-web-ide/bleoifhkdalbjfbobjackfdifdneehpo and that should have access to the serial port.

Thanks - I am now running the Chrome app. When I try to connect, both "TCP/IP" and serial ports show up.

When I tried to connect to /dev/wcusbserial, I could see the Espruino respond but the "Select a port ..." panel does not go away.

(In the Console, it still shows No navigator.serial even though the IDE could see the serial ports now.)

I also tried unsuccessfully to connect over Wifi. The 'port' is available but the IDE cannot connect to it.

Are you working offline?

No ... I'm on the network if that's what you mean.

I am now able to connect by Wifi! That gets me going without resorting to serial. Thanks.

Ok, so it might be a OS / serial driver issue.
Just to add: Telnet connection is much faster than serial connection - have fun.
