The question now would be cat5 or cat5e.

Can't really tell because I have to open the port, it's only labelled internally and it's pretty faded (it is likely 20 years old)

Easy to tell try to use the port. If it reads 1000 it's 5e if it reads 100 it's 5

Cat5 will often do gigabit perfectly well, particularly for shorter distances
