Jesus told them to make the people sit down, and food was distributed to those who obeyed. Does that mean those wandering around restlessly were not served?

Those who ate received not just as much as they needed, but more than they needed. In fact, it seems they wanted more than they could manage to eat.

"Would you like some bread or fish? "
"No, I would like caviar and croissants. "
Those who didn’t express a desire for the food on offer were not given any.

God’s word is what it is. If people would prefer it presented in a more palatable or interesting form from God, their only options are to accept it from God as given, or reject it from God as given.

When we demand God’s message according to some other recipe, there are plenty of cooks who will add this and that, and remove this or that bone, but we risk not getting God’s intended message, but some man’s ear-tickling souffle.

God sets the menu, we can only choose from what he is willing to serve. We don’t get to decide on and edit the menu of spiritual truth. Rev 22:18-19
