Electrum is a wallet that you can make it offline, this is different like online wallet such as binance, So if another person out there has his electrum wallet got hacked, your electrum wallet is not affected.
Binance isn't a wallet. It's an exchange.
I doubt bitcoin core is suitable for OP. For using bitcoin core, OP will have to download the full blockchain.
The best option for OP is electrum and if he doesn't want to use electrum for any reason, I would recommend
bluewallet as an alternative to electrum.
