An AppleCare+ plan is essentially an insurance product - providing cover for unexpected accidents or out-of-warranty technical failures that are not covered by the standard device warranty. Warranties are intended to remedy material or manufacturing defects that are identified within the warranty period. Warranties don't cover accidental damage or external influences.
It is notoriously difficult to prove that a crack is the result of a manufacturing or material defect. As such, screen damage is often excluded from warranty claims. A single crack that has no indication of an impact or point-pressure might be entertained as a warranty defect - whereas multiple cracks extending from a single point or chip will almost certainly be attributed to accidental damage.
Apple's warranty and AppleCare+ replacements may be a reconditioned/refurbished device - or new. As to what you receive will essentially be determined by availability, a new iPad potentially being substituted if a renewed iPad is not available within a reasonable timeframe. In either case, the device that you receive is at Apple's absolute discretion; the terms of Apple's limited warranty and AppleCare+ plan both reserve the right to replace an item with a reconditioned/renewed device that is indistinguishable from new.
All that said, Apple's standard warranty and AppleCare+ plans are in addition to any Consumer Rights that are applicable in your country/region.
Many users forego the optional purchase of an AppleCare+ plan - choosing instead to accept the consequences of accidental damage. For many, their household insurance policy (if any) may provide adequate cover for portable (but expensive) electronic devices.
Speaking personally, instead of choosing an AppleCare+ plan, for iPad I have always invested in a robust fitted case that offers substantial physical and drop protection - in addition to a laminated/toughened glass screen protector that provides additional damage protection for the iPad screen. With these precautions, despite inevitable minor mishaps, I have not experienced any damage to six models of iPad and iPad Pro - all of which either remain in perfect working order - or have been accepted for trade-in in perfect "as new" condition.
Your approach to risk and consequence may differ, but for me, damage mitigation across the full lifecycle of my iPad devices has been better served by physical protection - accepting that I am effectively underwriting a total loss should it occur.
