I spend half my time at a garden center looking up whether a plant is deer resistant or not. 
Plants that have strong smell and texture seem to be on their “do not like” list though as they say, if they are hungry without resources nothing is truly safe. They leave my sage, chives, rosemary, thyme, and lavender - all out in the open - alone. Mint too. I wish they’d eat that! I didn’t plant it but can’t get rid of it.
Flower/perennial wise I took a note from my neighbor who has been here for decades and bought - or she gave me - similar plants. Peonies, lilac, daisies, nepeta, astilbe, daffodils, wild phlox, iris, cosmos, cleome among those that are safe. Usually zinnias but last year mine got pummeled - I think that was a groundhog though!
