Do larger planar speakers produce more accurate sound?

I do not know if they do or not, but I really like my Maggies MGIIIa.  I enjoy the sound much more than box speakers.  I really do not care about deep strong bass; the Maggies produce nice clean bass and enough for me.

No one has mentioned line array (open baffle or not) speakers. I have only read about them, but I wonder if they might address the OP's call for "clarity" or "accuracy" or whatever magic word equates to what he wants.

I disagree with the comment about room interactions.  Most planar speakers are dipole and actually are designed for room interactions.  You send an identical  sound wave into a wall or corner and it is irrelevant if that sound wave was generated from a planar or cone speaker.  I agree completely with the comments about uniformity and ease of presentation, imaging.  I also agree with enveloping sound stage without being ever being harsh and yes they need power and dBels for all that to happen.  I've had visitors happily enveloped at SPL of 90 - 95 dB and never look at me like - what the hell.  I didn't hear QUICK mentioned and especially in the mid bass there is nothing like them.  The couch, chair and floor will vibrate -  musically and instantly.  Just don't expect anything to shake and rumble even with larger planars.  But shake and rumble generally ain't music anyway!!

speaking of line arrays, you should try a set of smaller maggies, quite affordable... and something definitely worth your experiencing - they are superb in what they do

"accuracy" in our hobby, of course, has no meaningful reference, so it is actually totally subjective ... as is the manufactured notion of stereo 'imaging', which, while very appealing when presented well in a good system, is also artificial... line arrays supposedly do the imaging thing less well, compared to more point-source style transducers
