My descriptor follows what most of the world uses. It's having the ability to pick and choose what I want. I don't walk into a supermarket and complain about all the different types of cereal on the shelf because I know I, and most other people in the world, have the ability to head straight for the ones I want and know there is still plenty of options for others out there who may not like the ones I like.
Society gives us options because businesses know that not everyone likes the same things. Do you get paralyzed when you walk into a library or a bookstore or do you just use your brain and a little common sense and just select what it is you want to purchase. Stores allow you to browse so I'm sure you've picked up an RPG you've never played before and skimmed through it. I'm sure you've looked at the back of the book that usually gives you a direction to go when going beyond the book you have in your hand.
GREAT NEWS!!!!!!
You have that RIGHT NOW with 5e. We've got the shelves lined with literally thousands of products for 5e between WoTC, DTRPG, DMsGuild, and your own imagination.
Before you come back with "But those aren't officially produced by WoTC directly", I'll point out that when you go into the supermarket, almost NONE of those items are produced directly by the store either. So either your analogy fails, or you do in fact have tons of options like you are wanting.
Since you raised the topic of Netflix earlier, a show with 100 episodes which are all inter-connected and build on each other is a deterrent for many to start that show. All production companies and distribution companies understand this. They adjust for this fact when agreeing to fund/distribute episodic versus non-episodic content. It's a major, HUGE factor for show balance, because the effect is so well known and studied and tested in that industry.
I will tell you right now that I will not watch shows like Arrow, The Flash, or League of Legends if I didn't start when they came out. They are all cross-overed for the most part, especially Arrow and Flash, and it's too much effort to figure out what and where and in what order to watch them.
It's also a reason why I haven't gone back to my comics from the 80s and not reread the Xfactor/Xmen/New Mutants because they constantly did cross over stories and it's too much a pain in the butt to try to figure out the order.
But to your point, you are 100% correct that I will often hesitate or not even bother starting a TV series if I know it's the same story that goes on for dozens of episodes. About 10 is my limit before I want a new storyline. And what you explain is exactly why traditional sitcoms were all resolved by the end of the episode.
