So sign up for 1 month, cancel immediately and then watch what you wish for the month. Netflix used to be a pretty good deal because they had a depth of great old content from the major studios. But now it's scattered all over the other services, and we've all seen most of their decent original content.
Doing it this way I'm subscribed to Netflix 2 months a year. Apple for 1 month. Disney for 1 month. That's a difference of ~$40 a year vs ~$500 a year.
Don't stress that you'll want to watch it and can't. You can just sign up again. Even if you do it 5 months a year, you'll be way ahead. Just use the psychology that if you sign up you cancel immediately. Now the default is to save money.
Don't get drawn into the idea that this is a luxury that you can afford. Wasting money is not luxury.
