On the other hand, try to put yourself in the position of someone who installed a wallet, had a backup and now wants to learn how to make transactions. You have to explain to that person what a public address is, what a change address is, what clipboard malware is, what a fee is and how to set it up correctly, what RBF is and how to use it in case the transaction gets stuck...
You don't need to explain most of those things. A person does not need to know what a change address is - a good wallet will take care of this for them. They should have some awareness of the fee, but again, a good wallet will pick an appropriate fee. They definitely don't need to know what RBF is, and many people still don't. Sure, it is good to learn about all these things, but if you are looking to keep things as simple as possible then they are not absolutely necessary in order to make a transaction. Paste in an address, double check it, choose how much you want to send, confirm. That's all that is absolutely necessary in order to make a transaction.
Explaining those terms to someone close to us is more like a discussion class. They can throw such easy questions often, which can be explained to them without wasting much time or referring them to an article that can distill the term down to their understanding. Even though the person cannot read to understand, carrying out the actions practically in front of them can ease their stress. Unless the person is far away then it may not be necessary, just follow the normal routine as you pointed out. But, if he's a neighbor, family member (old), or flatmate; those we have daily facial interaction with, explaining those terms is indeed simple and necessary.
