I don't own one, but the CZ is a very well-thought-of pistol, and could well be a fine choice for you for a first pistol. Promise us, though, that you won't rely on the mechanical safety, but rather that you will get some training and obey the Four Rules:
1. Treat every gun as if it is loaded.
2. Never let the muzzle point at anything you don't want to see destroyed.
3. Keep your finger off the trigger until you are on target and ready to fire.
4. Be certain of your target and everything behind and around it.
Notice that they are redundant - you have to screw up more than once to shoot something that doesn't need shot.
Since you made mention of visiting gun shops in Pennsylvania when you live in New Jersey, be aware that it is against the law to take delivery of a handgun in a state in which you don't reside. It would have to be shipped to a licensed dealer (FFL) in your home state, after which you pay the FFL to complete the necessary paperwork and hand over your pistol. That may or may not be worth the hassle and extra expense.
