on the hardwallet the wallet owner must scan the wallet for each transaction, otherwise the transaction will not be fulfilled

No, this is not safe, scanning QR codes for every transaction might sometimes lead you to a scam, there are too many reports about this, scammers tricking the QR codes since codes are almost similar and design and no one will notice if you will send your Bitcoin to the scammer address. Manual input is still good because you can manually check like checking the Bitcoin address last 3 digits and the first 3 digits.

here is one hardwallet that I have now is the safepal hardwallet, I prefer the safepal hardwallet because in addition to the many global wallets such as the multi-wallet that is in the trust wallet, it is a distinctive feature of the safepal hardwallet itself

Trezor, SafePal S1, and Ledger Nano S are the most secure wallet and I tend to agree with this. Both have a security feature and both also have pros and cons which do you prefer to use and the cheapest among them all is the SafePal wallet.

I saw a comparison of these 3 wallets that you may look at it too.

IMO, if you don't have a budget to buy a hardware wallet, still good to use an open-source software wallet, as long as your device is safe and make it sure didn't have a malware infection.
