Closing does not immediately impact AAoA. However, opening a new account will when the account reports. Closed accounts in good standing will typically continue to show up on reports and factor into your AAoA for 10 years. Closing doesn't make them go away and does not exclude them from factoring into AAoA. There's also an impact from having new accounts on your reports.
A score in the mid 700's doesn't really tell us enough to say whether or not you have a profile that can handle churning. Look at your AAoA and calculate how new accounts would impact it.
