Database optimisation is always a little bit tricky to automate :)

Generally we try and look for anything that constitutes a primary join
in the system.  The relationships between primary content type tables
and their array properties is quite important to index.  Also lookups
on refObjects, as this is constantly hit to determine the typename of
content items.

We use to have a good document on this back in the days of FarCry
3.0.  I suspect its still pretty relevant with the current schema:
