Imho hardware wallets are better for "every day use" than keeping life changing amounts on them.
So it depends on how much value is on those "few btc addresses with their private keys".

The funds OP doesn't need to spend in the near future can stay nice and easy where they are.
Also if there's a little more computer knowledge (for example to install a Tails OS USB and boot from it now and then with internet off), use of cold storage may also be a solution. But only if OP knows what he does.
