Just remember that once you send your coins to electrum , you shouldn't use that paper wallet anymore and their private keys were exposed.
You will need to create another paper wallet and send uour remnaining bitcoins to it.
When a Bitcoin holder moves bitcoins from one wallet to another wallet (two different wallet brands), it is vital to move fund from an old wallet to a new wallet. Avoid importing private key from one wallet brand to another because if the wallet brand used to create that wallet is bad, has backdoors, compromised, the second wallet brand can not save your fund.
I agree with your advice to abandon the initial wallet (paper wallet in this example), and move it to a new wallet (in this example, Electrum wallet).
I strongly advice that you buy a paper wallet.
It is hardware wallet, not paper wallet?
