Interested in growing some marginally hardy tropicals in zone 6 NE Ohio (i can protect them as needed)

I really want to experiment with some tropicals here in zone 6 in NE Ohio but I need some more ideas on want to plant. But first, a little description of my climate: winters here are cold but below zero only happens every other year and if it does get below zero, it only happens for around a day or two, we also have tons of snow (and I mean a ton) which I think is good for insulation. Winter sunburn isn’t really an issue since sunlight is limited in the winter (thanks Lake Erie), it can stay consistently below freezing but only usually in the teens, 20s, and 30s. I’d say we’re a cold 7a and a warm zone 6. Summers here can also get pretty dry at times so drought tolerant options are appreciated. I also live in the woods where there’s tons of leaf litter and wind protection due to lots of trees. Shade tolerant options would also be appreciated. 
Anyways, here’s my current list of bucket list plants: Sabal minor since they can handle wet soil and shade which happens in the more forested areas of the yard, some sort of illicium species since they can also handle wet soil and shade, Aspidistra elatior since they are shade tolerant and easier to find, Cinnamomum checkiangensis since they are the most cold hardy camphor tree and I absolutely love the leaves and the smell of camphor trees, Yucca rostrata since they basically need zero cold protection here and I can plant them in a pure river rock bed I have. I am open to more suggestions as long as a mini care guide is given alongside it. Thank you for responding.

Consider building a conservatory.
