From my experience with cichlids its best to steer on the side of caution.
I avoid small fish like tetras and fish with long flowing tails with mine because I know for certain that someone in my tank would destroy them.
I have a large tank in my living room specially for my dwarf cichlids (rams, keyholes, firemouthes, kribensis)
My dwarf cichlids are certainly friendlier than oscars and malawis, but cichlids will be cichlids and I still have to be careful who goes in the tank with them.
I stick to fish about their own size with no fancy tails just to be safe.
I'd say avoid cichlids like the plague with your betta, the odds are it probably wont end well.
Instead maybe think about small fish like neon tetra and harlequin (:
