There is the question of which devices you store the wallet on and whether you can sync those up. Not all wallets can sync across devices. There is where you have to research each one and whether it fulfils your needs.
Just take your time, read and take notes. It all starts to make sense eventually.
Oh, another tip, guard the keys to your wallet very carefully. Many people have either been tricked, or made silly mistakes, revealing their keys and some one has then stolen their coins.
Again, read up on this and inform yourself. In the crypto world, you are responsible for yourself.
