I have weighted raster data converted from polygons with different categories.

I have ArcGIS with 3D Analyst extension, unfortunately do not have Spatial Analyst, and I would like to use QGIS to make weighted sum overlay analysis, probably using ordered weighted averaging.

I found some similar questions but nearly all explained vector overlay analysis. Here grids (tif, img etc) will be used.

SAGA has an Ordered Weighted Averaging tool which lets you import grids as an input. You can access this from the Processing Toolbox:

Ordered weighted averaging tool

The QGIS documentation for this tool appears blank, but there is some information in the SAGA documentation.
