Is there any recommendation or best practice?
The context is that of a web application running on desktops. The number of items is variable ranging from 4 to around 10.

You added that the number of items ranges from 4 to 10. This can be OK, but we really can't tell without knowing the context and the size of each item.
I suggest that you make a mockup, either a drawing or something a little more realistic to give a idea of how it will look like. This way you will probably be able to judge yourself if you are still in the acceptable range for using a carousel.
Also I think your question is a bit 'reverse'. You should first look at what you want to display and then choose an appropriate way to display that information. Not the other way around.
