I would need to reproduce an ArcMap cartography project in an equivalent QGIS project. in the ArcMap version the symbolization of some layers is done through the "Unique values, many fields" method, ie:
how can i "translate" this method in QGIS?

Select the Categorized type in the layer styling dialog then click on the ''ε'' symbol at the right of the column drop-down selector then you could construct an expression to concatenate as many field as you want for unique value symbology.
For three field you would use :
"Field 1" || "Field 2" || "Field 3"
The ''||'' symbol concatenate the field together, for better readability of your different categories you could insert a space between the field (
"Field 1" || ' ' || "Field 2" || ' ' || "Field 3") (edit : Arcgis use a '', '' as a separator)
After validating your expression just click the Classify button...
