Hi!

I recently started photography and I purchased a Sony a7iii (loving it). I was curious - is there any reason to shoot RAW files when using the send to smartphone function via the PlayMemories app? I know the camera automatically compresses the file into JPEG when sending to the smartphone so it's not actually sending a RAW file, but I wasn't sure if the end quality is better when the original file is in RAW format? Is the transferred file going to be better because the original file started with better (raw) quality? Or should I just save myself the space on my memory card and shoot in JPEG? 

Quality wise there is no advantage in shooting RAW and then letting the camera convert to JPEG when transferring. That is what it's doing anyway when shooting JPEG.

The advantage in shooting JPEG in camera though is that you get to choose the creative style and have a little control over how it processes the files.
