Among all the wallets you mentioned here, I can recommend you a hardware wallet to keep your Bitcoins for the long term. If you have the money to buy a hardware wallet and you want to keep your Bitcoins, you can buy a hardware wallet, it is a very safe wallet to keep your Bitcoin investments. If you do not have the money to buy a hardware wallet, then you can use a software wallet, in that case you keep the wallet's seed very safe so that no one can access it. However, I do not want to recommend you to use a centralized exchange wallet because centralized exchange is not safe for you and an investor.
