Desktop Wallet - Hold your coins on your desktop. I recommend the Exodus wallet for most people. Exodus currently supports over a dozen coins.
For more advanced users, the creators of Exodus have also created the Eden wallet. The Exodus Eden wallet will provide support for ERC-20 tokens, whereas Exodus will not. Note: Eden is unsupported, pre-release software - things are likely to break. Eden is for "advanced users".
Add extra security in any way you can. Use Google Authenticator for two-factor authentication on all accounts. Use LastPass password manager to create secure complex passwords. Write down your seed phrase and save it somewhere on paper. Keep your wallets updated.
