Picking a bat is such an individual thing...
If you haven't already, do a little research about turn models. I found that helped some. And don't overlook birch among your options--some say it's a good compromise between the hardness of maple and the (relative) durability of ash. My son's favorite wood bat was a birch Rawlings Velo -- https://www.rawlings.com/product/R110BV.html // currently on sale. Although to be honest, I think a lot of his fondness for his birch bat was b/c he said it "looks really dope." (He is a PO now, so we have a bunch of bats gathering dust in the garage.)
When my son first needed a wood bat, my process was un-scientific: I looked for decent-but-not-expensive wood bats on sale and bought several for him to try--different woods, but turn model and weight distribution consistent (I hoped) with the metal bat he had been using. Son used those at practices for a bit, chose his favorite pretty quickly.
And maybe this is too obvious to mention, but once your kid picks the bat he likes, I'd try to grab at least one more while they are still on sale. Everyone has their own budgets and predilections, but for a 2022 I'd have a hard time spending more than $100 on a wood bat. Technology doesn't come into play to the extent it does with metal or composite bats, and any wood bat is always one swing away from being kindling...
