As for Bluewallet wallet it is only for android OS and IOS not available for desktop version, while OP is looking for windows version then it is better electrum.
This is not true, BlueWallet is a desktop wallet, but it is available on MacOS, though it is not available on windows, and like you said it is available on mobile for both Android and IOS.
Electrum Wallet also has a lot of additional security features to keep the Bitcoins I own safe, and this makes it one of the most secure software wallets out there, in my opinion.
Electrum wallet is self custodial and a well reviewed open source wallet, making it a recommended option to hold BTC, but take note that your wallet is only as secure as the device that you use it on, meaning if you use your Electrum wallet in an unsafe environment, your funds are prone to hacking. Electrum also has features such as setting up a multisig wallet or extending your seed phrase with a passphrase for better security of your funds.
