Spoiler,
This is really a personal preference thing. You don’t need to think long term – you can start in the short term.
I lived without a TV for a few years and its really not a big deal. I view a TV as a nice to have (we have one now).
Are you going to have internet at home? If so, you have a TV.
Your first year of marriage should NOT be boring 🙂 If you are having adjustments to marriage, you should be proactively working on them. There are plenty of things to do so you won’t be bored.
Either way is fine though. Good luck with your decision.
