I’ll add that the whole “beginner’s guitar” thing is a bit suspect in the first place.
What people generally mean by “beginner guitars” is ones at the cheaper end of the scale, on the basis that you probably don’t want to invest too much in a new hobby to start with. What “too much” is will depend on your bank balance: if you are a billionaire then a $25,000 vintage Les Paul could be a “beginner guitar”.
There are some “beginner” guitars which are low-end instruments, often sold in a pack along with a cheap amp, aimed at providing an all-in-one package for the new starter. These are often very poor quality and are actually possibly the worst thing a beginner could get, as they will make learning hard.
IMO any guitar that you learn on should be an instrument that a professional player would be reasonably comfortable gigging with. Most modern guitars costing around $150-200 (USD) upwards fall into that category.
As a great example of that, Mike Rutherford (Genesis, Mike and The Mechanics) can afford to have pretty much any guitar he wants, but he recently revealed that he gigs with $200 Squier Bullet Strats, a guitar many people would consider a “beginner’s guitar”.
A guitar costing $500 or more should be a high quality instrument. As you go up in price, the law of diminishing returns applies, and you get increasingly less and less for your money. Above around $1,000-$2,000 you are mostly paying for cosmetics, like exotic woods or branding.
