Just an anecdote: when I switched to nylon strings not many years ago, to play Bossa/Swing in a Jazz Ensemble (amplificated), my choice was the Manuel Rodríguez Caballero 10 Cutaway "Electric Neck" (= 46 mm nut), which was cheap, had a pickup and a very nice sound BUT:
Coming from steel strings, I thought it would be self-evident to pick a guitar with a "steelstring" neck. I ordered without a test directly from the internet. Later on, when I was used to play that guitar, I realized that the main obstacle to play comfortably was this 46 mm nut. When first trying a standard 52 mm guitar - admittedly with a flat neck (Manuel Rodríguez FF Cut) - it was like a revelation: far more easy to play, I made vast improvements in very short time, which would have been impossible with the slim neck.
So my recommendation is: try as many guitars as you can - maybe a "classical" friend can help you. And try to avoid thinking "steelstring". A wide nut might look strange, but - IMO - is easier to play. The CG is a different instrument. And the first pick will not be your last.
When advising a friend for her first guitar after many years, I went to a big shop and tried everything in her budget range (around € 300.-). The guitars which impressed me most were Alhambra guitars. She picked a 1C "Señorita" model (shorter scale, 636 mm, 50 mm nut), because she's very small in height. Great sound and playability. But also the full-size models were impressingly good for that money. If you need a pickup in your guitar, I'd recommend Manuel Rodríguez C12 or A Cutaway, but I'm sure there are other manufacturers, that do a good job as well.
