Hi anon I’m happy more people are getting into true poetry. Start with learning scansion or how poetry is created, this helps you appreciate what you are reading, next you should get a general timeline of English poetry/canon and start with a specific era that interests you (as in Elizabethan, Romantic, Victorian, Modernist etc) Byron has a lot of longer narrative poems so I would start with his shorter poems included in the collection titled “Hebrew Melodies”. Write poems whenever you feel inspired, just make sure they are actual poems and not free verse.
