Yamaha currently offer two acoustic guitars with necks which will meet your stated preqs.

The F310 which is generally considered a beginners' guitar because of its marketing and pricepoint. It's a pure acoustic Dreadnought and loud. As long as Dreadnought size and shape fits, it's perfectly fine for learning and playing at the skill level expected of those first few years.

The APX 600, but which is a slimline cutaway electric acoustic. I own one of these. I love it. Brighter, not as loud, but still projects well in any room, and of course with integral amplification when louder is required.

As you move up their respective status segments, the scale length, string tension, neck profile, radius, string spacings, and sometimes nut widths, all change, so e.g. APX 700 & 800 although constructed of different materials, doesn't mean better all round, but different. Be aware of that.

Offerings from other brands for smaller hands. Look to their neck profiles, scale length and string spacing in particular. Most acoustic guitars have a not disimilar fingerboard radius.

As a player with smaller hands, I also have a Cort Concert acoustic with a modern C but constant profile neck and 11mm string spacing with a scooped bridge for lower tension & greater sustain among others. I like playing it very much too.

Design implementation should be of a higher priority in the first few years than what prestigous wood a guitar is made of, kudos a label on the headstock affords, or price, the latter not at all an indicator of the foremost needed characteristics in a guitar which fits a person or optimal for the learning and progress purpose. Sure a higher the price is usually an indicator of increased material, mech and overall build quality compromised by the complexity of demand and brand perception marketing, but it's no indicator of fit.

We'll always play a guitar which is a good fit better than one which isn't regardless price prestige.
