In my opinion 1 wallet is enough to keep your assets safe. I recommend a blockchain wallet because in addition to the high level of security and the occurrence of a scam it is almost impossible because every transaction is stored on the blockchain.
Your level of security consciousness is good but creating many wallet hardware I won't advise, it may still be detrimental so that you won't still end up loosing the protected when the password becomes too numerous.i will suggest you use a maximum of 3, because you may end up confusing yourself the more.
