I'm not good enough with pole beans to talk you into a particular variety, as I am still in the experimenting phase myself, always on the lookout for a better one.
But...couldn't resist sharing a link to a great website that I have purchased seeds from in the past. They have an enormous variety of pole beans, and keep scrolling and you'll find they have tomato and bush bean seeds as well. Shipping is reasonable, prices are fair for such a wide selection of hard-to-find heirloom varieties.
I've purchased some pole and crowder seeds and they were pretty much 100% germination and grew true to form.
Their page titles Appalachian Heirloom Beans:

Have fun with it! I love this site.
