I always felt this was a bit generational or budget related.
Growing up my food was plated, because we had no money. So a certain amount was cooked and then given to you. The issue was I had to eat everything on my plate, so I had little say in the matter. Even if I didn't want it, I had to sit there till it was eaten as we didn't waste food.
So I took the opposite with my child. Food should not be something controlled or a battle zone, meals should be fun, and we have always used serving dishes, I shove it out in thr centre of the table and there is more than enough for everyone. I even do it with sandwiches.
My daughter does eat everything on her plate, but not because I ever suggested it, simply she takes as much as she wishes, finishes it, and if she wants more will have seconds or pick as we are chatting.
Our friendship circle is the same, nothing is plated, hence I thought there was a generational element to it also.
My mother in law was the same, she plated, but they had no financial issues, but curiously. both sets of my grandparents didn't, they were Italian and feeders, and food was always in the centre of the table to help yourself to.
Dinners at their houses was always a lot more joyous with chatting and sharing, than the miserable as fuck "there's your tea, eat it" scenario we had going on at home.
