The manual mentions the use of a load() method but I can't find it nor figure out how it would work. Should probably be suggested here. So if anyone knows...

@nyalldawson can you show how the load() method can be used here, please? Thanks.

That load method is deprecated, we shouldn't mention it: https://github.com/qgis/QGIS/blob/master/python/plugins/processing/tools/dataobjects.py#L111
(it won't work as desired anyway)
If you want to do it by hand you'd do something like:
results = processing.run("native:buffer", {'INPUT':'/home/nyall/dev/QGIS/tests/testdata/points.shp','DISTANCE':10,'SEGMENTS':5,'END_CAP_STYLE':0,'JOIN_STYLE':0,'MITER_LIMIT':2,'DISSOLVE':False,'SEPARATE_DISJOINT':False,'OUTPUT':'TEMPORARY_OUTPUT'})
buffered_layer = results['OUTPUT']
QgsProject.instance().addMapLayer(buffered_layer)
