As a middle school student, my brother likes old-fashioned poems and has a bright future. It is important to lay a good foundation. Don't learn those old-fashioned styles that dare to call themselves "poems" by rhyming. I suggest you learn metrical poems first. Don't comfort yourself with "metrical thinking". In fact, metrical thinking is very simple. In ancient times, children learned it.
As for submission, it's easier for your local Evening News Literature and Art Department to publish, but I doubt the poetry literacy of these supplement editors. I don't know how you are there. Anyway, I can write two or three old-fashioned poems published in our evening paper.
