Hey your concerns are legit but these hacking happens mainly due to you using your wallet on a public wifi, or having virus on your machine, or sharing your details like private key or seed with others. I would recommend you Electrum wallet if the total bitcoins value is less than 100 bitcoins, if it's more than Trezor wallet those are the most secured wallet, but use them only if you plan to hodl a big amount of bitcoins.
Those are definitely common causes but you would need perfect online security to pull it off, which is unlikely. At the end of the day, if your private keys are online, your coins are always at risk. Electrum is a great wallet, but I wouldn't keep even 2 BTC in it.
If you absolutely don't want to spend on one, you may as well create a cold paper wallet -- the only important part is to make sure your private keys never touch the internet after all.
