MacBook Air is connected to an LG Ultrafine monitor
Thunderbolt cable connecting them provides video signal and charging.
Should I refrain from connecting the MagSafe charging cable or does the hardware detect this and handles it properly?
Thanks,
Enrique
See information in Charge your MacBook Air or MacBook Pro - Apple Support including the following
You can also connect a USB-C or Thunderbolt display that provides power, such as the Apple Studio Display. If your display provides power to your Mac, you don’t have to connect a separate USB-C power adapter.
Your Mac charges over only one port at a time, so connecting multiple power adapters to the USB-C ports and MagSafe 3 port (if present) won't charge your Mac faster. USB-C charge cables also support different maximum wattages (W). For example, the Apple USB-C Charge Cable (1 m) supports up to 60W and the Apple USB-C Charge Cable (2 m) supports up to 100W. If you connect more than one power source, your Mac charges only from the cable and power adapter or display providing the most power.

As stated my display does provide charging. So from your reply I take it I should just keep using the USB-C cable to the monitor only.
