I will recommend passport.

Some people also recommend Keystone.

I would have recommended Trezor but the recent coinjoin with the help of Wasabi makes coinjoin to be censored and no privacy anymore as the transactions are monitored by Chainanlysis.

As for Ledger Nano wallet, it has been on of the worst I can not recommend anyone. I do not recommend the wallet before because they were careless with customers data and also the secure element in all their wallets are all close source.
