hi guys,
im a new engineer in search of some experienced suggestions in regards to communication methods selection,
i need an opinion on choosing the most accurate (with least errors occurring) and fastest communication method. The board that im going to use has the following:

Gigabit Ethernet (1000 Mbps)
Ethernet Interface (10/100Mbps)
USB1.1
RS-232, RS422 or RS485, software configurable

thank you so much in advance

It depends on the device you need interfacing.

If you can choose the interface among the quoted ones, certainly you should choose Gigabit Ethernet since it is fastest. If you have more than one device and gigabit ethernet is busy you can :
1-Use a hub or switch
2-Use other interface available since the speed is suitable for you application.

If the device comes with an interface it is basically due to two reasons:
1- The interface is suitable for the device.
2- When the device was manufactered there was no better interface available for its purpose.
