The most secure , "active" wallet would be a hardware wallet integrated with a full node . One way to do this easily is to run your own electrum server https://github.com/chris-belcher/electrum-personal-server https://www.youtube.com/watch?v=1JMP4NZCC5g and than integrate electrum wallet with your HW wallet and connect to your electrum server.
Running an economic full node greatly improves your security and privacy and the security of the network as a whole. This means that you must link your full node to your personal wallet . This is typically done with electrum personal server + electrum (or these 2 and a hw wallet is better) or using a full node like https://getumbrel.com/ is another example
