If the transaction hasn't been confirmed yet, and it's RBF enabled, then you can cancel it otherwise, no, there isn't much you can do sadly.

About that transaction? Unlikely, unless it is flagged as RBF and yet to be confirmed, as OSS has said above.

Going forward? You need to examine how your bitcoin was stolen and take steps to address the vulnerability. Did you download a malicious version of Electrum? Do you have malware on your computer? Do you need to format your computer and start fresh with a clean OS? Was your seed phrase compromised? Do you need to find a more secure method/location of backing it up? Do you have other bitcoin/altcoins which are now also at risk and should be moved to safe wallets?

I kept on wondering how a set-up electrum wallet got hacked when every keys are saved perfectly, could it be that a close friend to op got access to his keys?
 
If your electrum wallet is properly kept secured and backed up, every keys saved in a private place especially offline, downloaded from a right electrum website, any possibility that the coin in the wallet could be stolen by unknown hacker?

It could be, but it doesn't necessarily have to be. Electrum is only a software wallet. Anything which compromises the device it is installed on can compromise the wallet and potentially steal the keys or coins held within. If the device it is installed on is connect to the internet, then there is a significant risk. If the device it is installed on is used for daily browsing, visiting a variety of websites, downloading files, social media, emails, etc., then there is a very significant risk.

The "offline" part is the important part of this sentence. If you are using Electrum in an airgapped set up, with it installed on a device which never connects to the internet, paired with a watch only wallet on an internet enabled device, then such a set up done correctly is very safe and very difficult to be hacked. If, on the other hand, you are using Electrum on an internet connected device as described above, then it is significantly less safe.

Since you don't really know how your seed was leaked, I think cleaning up your OS and moving all your crypto to a new wallet in a secure device would be the best step. After that, start asking the questions leo listed up above.

In the end, you might find nothing, but it's a good practice to do. Don't forget to check your e-mail, crypto accounts, and other stuff like that to make sure they're not hacked, change your password etc if necessary. If you were attacked by a keylogger, then that step might become necessary to protect your accounts.
