In regards to private key management, there are two main types of wallets: custodial wallets and non-custodial wallets. Coinbase, Kraken, and Gemini are examples of custodial wallet providers.

You should write down the seed phrase and store this information in a secure place. Just like private keys, seed phrases should always be kept secret. Assuming that no one else gains access to your private key or seed phrase, you should be able to use your seed phrase to recover funds.
