The problem in keeping the coins with third party service providers such as Coinbase is that they can freeze your coins without any warning and then ask KYC documents in order to get back the access. As such there is no need to store coins in third party wallets. You can easily set up a desktop lite wallet or an online wallet and store your coins. It is going to be as secure as a Coinbase wallet. Just remember to take the basic security precautions, such as email confirmation and 2FA.
