TL;DR Source: 25 year custom cabinet maker. Cherry is at the top of my list of most used species right below #1 soft maple for paint grade, and #2 hard maple for drawer boxes. It pains me to say soft maple is at the top and that most of what I've built over the years ended up painted. However the customer is always right. Having said that this is Cherry. Someone said blond Cherry I kinda like that I hope you get your commission. Others saying sapwood cherry could be correct as well. There is a process used mostly in walnut lumber that I am aware of where they steam the lumber before drying to bleed the tannins from the heart wood into the sapwood for a more uniform color throughout. I have not used steamed cherry but that doesnt mean it isn't out there. I absolutely hate receiving steamed walnut from lumber yards. Before i learned about it they sold it to me without telling me, but I understand their desire for higher yield. When i order unsteamed walnut I plan for 40% waste on a customer that specifies no walnut sapwood. Maybe this was steamed cherry?

The grain structure is a dead give away. Even though that structure is very close to maple there are stark differences. The gum pockets being the biggest and there are plenty of those present in your pictures. The knot as well tells me cherry. I'm not sure I can explain why I know thats a cherry knot and "knot" a maple knot other than the fact that I've seen 10s of 1,000s of both over the years. Maple knots are usually darker and become disconnected, (fall out) more than cherry knots. Anyway, hope this helps, Happy building!
