I have a few wallets that I have used and I might recommend them to you since I consider them to be extra secure, adding to the fact you can link some of those wallets with two factor authenticator.

For beginners like you, the user friendly bitcoin wallet that I want to recommend is blockchain.info wallet, even now I am still using it to store bitcoin and haven't encountered any difficulties. Desktop version, look for exodus.

For storing ERC20 tokens, I would recommend that you consider using myetherwallet, although you are unable to configure 2FA, but its secure enought and gives different options to access your wallet. You can even install metamask extension on your google chrome browser.

For storing XEM and DIMCOIN, I use the Depotwallet, the new version that was recently launched is so user friendly and easy to navigate, and the transactions are very quick. I also use cryptonator for storing litecoin and monero.
