To get a TV or not?

If I'm only going to do Netflix,  should I bother?  What if I buy Hulu?  What TV do I get? How do I pick a good one? Do I get one that's a smart TV? Will it be able to do Netflix and Hulu on its own? What about an Amazon firestick?  Yikes I really don't know much about these things.  I'm moving and I haven't really had a TV for real in a few years.  I've gotten by so far.
