I formatted an SD card in a Sony camera and want to know whether the deleted RAW files (.ARW) can be recovered. Are there recovery tools that support Sony RAW files specifically, and does formatting in-camera affect the chances of recovery?

Free, open source, cross-platform software PhotoRec can specifically recover many RAW formats, including Sony ARW (as well as Canon CR2, Nikon NEF, Pentax PEF, and others).
Although the interface isn't particularly slick, the underlying functionality is the same as any proprietary program, and I'd be surprised if any of the more expensive options can recover anything this can't. Of course, if this fails, you can always try one of the demos of the commercial software to see if it can do any better. But I don't think they actually have any extra magic sauce — in fact, I've seen anecdotal reports that PhotoRec is more thorough.

Yes—Sony ARW files can often be recovered by standard photo/file recovery software. PhotoRec is a well-known free, open-source option that supports many RAW formats, including Sony ARW. Other recovery tools may also work, and some commercial options offer trial scans so you can see whether files are detectable before paying.
That said, success depends heavily on how the card was formatted and what happened afterward. Some Sony cameras may send an SD ERASE/TRIM-like command during formatting. If that happened, recovery software may only see zeros, making normal recovery impossible. Continued power to the card can also allow internal cleanup routines to further reduce recoverability.
Best practice: stop using the card immediately, remove it from the camera, and try recovery on a computer as soon as possible. If software recovery finds nothing and the images are critical, a specialist data recovery lab may be the only remaining option.
