On-chain TXs sent from Exchanges typically are overpaid, since they prioritize user experience over minimizing fees. When you use a wallet that gives you more control over the fees you use, such as the OP did by using Electrum, you can tweak the fees to a better rate. This does entail a certain risk in terms of TX delay, if you set the fee rather low and/or there is a sudden sustained spike in TX activity, making the mempool more competitive and generally relegating TXs with lower fees.
If the TX is created with the RBF flag, then one can resolve the issue without too much hassle. It’s just that the learning curve over the first time or two that you encounter this may get a little bit bumpy, providing some minor arrhythmias until you get used to it and know what to do to resolve it.
Note: Just for the record, the OP’s TX went through after performing a RBF, as can be seen by going over the small amount of posts in this thread.
