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?

The given payload figure is for a fully expendable Falcon Heavy. In fully reusable mode, the payload is 8000kg to GTO, still more than Arabsat 6A requires and allows for up to 2000kg of GTO ridesharing (potentially more if they can be dropped off in LEO on the way, but I don't know if that is ever done).

@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.

1 this reflects the likely cost as of the time when Arabsat 6A's launch was being negotiated; Proton-M has since been price-cut to be competitive to Falcon-9

The given payload figure is for a fully expendable Falcon Heavy. In fully reusable mode, the payload is 8000kg to GTO, still more than Arabsat 6A requires and allows for up to 2000kg of GTO ridesharing (potentially more if they can be dropped off in LEO on the way, but I don't know if that is ever done).
