Coinos for LN
Electrum for desktop L1 BTC although I have not tried many of the others. Electrum also provides the info required to build your own cold storage basically for free and independent of rentseeking third party HW touts.
You can build your own very durable cold storage- but first learn to use Bitcoin wallet/s (BTC & Lightning Network) for just doing small test/trial transactions and enjoying the amazing liquidity and integrity of the protocol!
If possible only use Linux OS for large BTC transactions and storage.
