I you feel you aren't capable of holding multiple keys on your own then there is an option that offers paid multisig setup like Casa which ensures that your keys will be will be stored in multiple places but its all based on trust which is against the nature of bitcoin since it encourages trustless system.

I will suggest you go for hardware wallets that are better than SPV wallets cause its less likely to be affected by malware and no burden of managing multiple keys.

But there are different kinds of wallets available for different user needs so pick yours based on your needs. And if you are just okay with a small amount then single signature Electrum wallet is enough along with passwords that ensure unauthorized access when device gets stole and buys you enough time to import the wallet with seeds and move the balance in that wallet to the new when the person is trying to brute-force your password.
