I'd probably do the same with other similar services like HBO or Amazon Prime. Subscribe for 6 months to 1 year, watch all the content I am interested in and then cancel my subscription.
I remember rarely launching the Netflix app for a long, long time, and constantly debating whether or not to maintain my subscription, and then they started releasing "original(ish)" content that, frankly, was pretty damn compelling.
I still go through spurts where I find difficulty finding something I want to watch right now, but recently, I'm finding that's less and less Netflix's fault relative to the other cable-cutting services.
So it doesn't continually make sense for me to keep paying Netflix every month when I can subscribe for 3 months every 2 years and watch the content I like. Then cancel subscription and switch to HBO/Amazon for 3 months and catch up with my favourite content there.
It's much more economical than being subscribed to all 3 at the same time. And any single of these services does not generate enough content for me to keep me interested long term.
You can't replace quality content with mediocre netflix originals. At best, 4 or 5 of those you listed are watchable, while the rest are just space fillers, trying to distracted from the loss of a huge number of popular shows.
Hulu, Amazon, HBO, etc all provide more quality content per dollar than Netflix at this point.
Another issue is outside of US the catalogue is very small. I was living in UK at the time I subscribed to Netflix and the catalogue was much smaller than US one.
