Will these floorboard cracks be a problem?

not at all, easy to replace. The old screws are thinner, so all good.

I'd use 5x50 countersunk woodscrews. Screwfix gold are quite good and inexpensive. Get a countersink bit while you are at it.

You dont even have to replace, just add one next to each drywall screw if you like.

Just make sure you know theres no pipes/wires underneath where you are screwing if going for fresh wood.

Thanks alot for your input i appreciate it. My builder seems to be taking shortcuts which is why I'm seeking third party advice. In regards to the hardiebacker boards, do you have any knowledge in the correct application of them? Ie type of screws, priming etc?
