Is it just me or does a falcon heavy seem like a bit of an overkill to launch Arabsat 6A?
Falcon Heavy - GEO payload: 26,700 kilograms
Arabsat 6A - weight: ~6000 kilograms
Wouldn't some other launch options be more appropriate or is there something about the launch of Arabsat 6A that needs the additional power?

6000 Kg is actually pretty big. I am sure SpaceX offered some discounts to attract a customer for Falcon Heavy.
So I will ignore the other options (Atlas 5 with side boosters, Ariane 5, or Proton) and focus on why not a Falcon 9.
Falcon 9's numbers are lower to GTO, Wikipedia has it around 5500kg reusable. 8300kg expendable, and SpaceX's point is, if you are bigger than a Falcon 9 can handle and still land, better off moving to a Falcon Heavy.
Also there are different GTO orbits, the higher the 'energy' the less work (aka burned up fuel) the satellite needs to do to get to a circular GEO orbit. SpaceX does aim for a lower of the set, usually to allow recovery.

@geoffc's answer explains why Falcon Heavy over Falcon 9, but the reason for why not any of the other options is likely cost.
It's difficult to say with certainty what the launch costs would be, since costs are negotiated per launch, and are affected by a large number of factors (target orbit, payload mass, fuel costs, ridesharing, etc). Estimates put Falcon 9/Falcon Heavy's main competitors Ariane 5 at around $178M, Atlas 5 at $109M-179M, and Proton-M at about $100M1. Expendable Falcon 9 and Fully Reusable Falcon Heavy both cost an estimated $90M, and as @geoffc pointed out, FH has greater GTO capacity than F9, so the launch could use some combination of more favorable orbit and extra ridesharing capacity to reduce the effective launch cost.
