Gosh that’s a hard question, because poetry is such a personal thing.
I’d say start with a really good anthology, like the Seamus Heaney and Ted Hughes edited Rattle Bag. It’s just basically some of their own favourite poems arranged no more cleverly than alphabetically. Then you can decide for yourself what touches or entertains YOU. Don’t listen to anyone else’s opinion as to what’s “good”, or “bad”, or “sentimental” (not that there’s anything wrong with sentimental). It’s up to you. It’s what touches you personally that matters. I was put off Emily Dickinson for years because of someone else’s opinion. Now I relish her: “Unable are the loved to die, For love is immortality.” How could I have allowed myself to be put off the woman that wrote that?
Others I’ve been reading a lot lately: Edward Thomas, Robert Frost, Thomas Hardy, John Clare, Seamus Heaney, Patrick Kavanagh (who also wrote Tarry Flynn and the Green Fool - two of my favourite books.) But those are just some that I like personally. Everyone will feel differently. Don’t listen to me. You decide for yourself. I also love the much misunderstood and looked down upon Kipling.
You can find great resources online at sites like Poem Hunter Just have a browse and enjoy.
Edit to add a link to Poem Hunter (I confess I’ve never listened to the readings on here, though Seamus Heaney and Ted Hughes reading their own works are always a luscious treat).
