The USB Printing option in Cura is un-maintained (Ultimaker printers don't use it anymore). Connection is supposed to be automatic so there are no options to pick a port, or a baud rate.
Check in the Cura Marketplace under Installed and scroll down to "USB Printing" and make sure it's installed and checked.
When you are sure it's installed and active...
Turn off the printer. Close Cura. Disconnect the USB cable.
Start the printer, let it finish booting, and re-connect the cable. The printer should re-boot when it sees the 5 volt signal on the USB cable.
Make sure no other running software is accessing the port. The only thing connected via USB should be the printer.
Start Cura.
Go to the Cura Monitor tab. Sometimes it takes a minute or two for the connection as Cura cycles through the available ports and tries different baud rates until there is a response that Cura understands.
That all works fine with my Ender 3 Pro.

Cura 5.7 is here and it brings a handy new workflow improvement when using Thingiverse and Cura together, as well as additional capabilities for Method series printers, and a powerful way of sharing print settings using new printer-agnostic project files! Read on to find out about all of these improvements and more.
S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
(Sorry, was out of office when this released)
This update is for...
All UltiMaker S series
New features
Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.
