Answering my own question again. It does look like leaving everything alone works pretty well. Primary key unchecked results in a primary key being set up with the id column as shown in grey. This caused a problem when the layer had a pre-existing non-unique id column. Works fine if the existing id column has unique values, or does not exist. Leaving the geometry column unticked seems to create a geom column (as shown in grey). If a spatial index is needed and wasn’t ticked, a warning will show in db manager afterwards and it is easy to create one from there.
Just needs the documentation update to say not to worry about it. A bit like the lack of documentation on how to upgrade an existing install. It doesn’t seem to matter what you do, but you can waste a lot of time trying to look it up if too cautious.

Can anyone recommend a good reference on what options should be selected? It seems to fall into a gap between PostGIS documentation and QGIS documentation and I can’t find any information on what should be selected in what circumstances. In particular Primary key – should this be ticked and the existing id field selected? What happens if it is left unticked? Geometry column – is this needed? Objects still seem to have geometry if it is left out. Create spatial index – this sounds like a good idea, but the one youtube tutorial I found (Klas Karlson) he left it unticked and said the layer already had everything. Is it needed for some source formats and not others eg shapefile vs geopackage? Convert field names to lower case doesn’t sound very useful, but I presume it is there for a reason, does anyone know the circumstances that would be needed?
