A good tip I read is to wipe down the pan with such a thin layer of oil that it's as if you made a mistake and want to remove the oil with just the paper towel instead. It should really be as thin as possible, and you'll see it sort of glaze over as it drys on the stove top. After about 6 months of this, using the pan about once a week, it has been truly non-stick for a while.
Basically following this guide: https://www.cuisinel.com/care-use
So some of it is what you expect, cast iron is basically non stick for lots of things (AKA I would never use anything other than cast iron for pancakes/etc), but I keep a couple Henckels Capri Notte Granitium pans we picked up at cosco handy for the morning eggs. Those seem to be the survivors at this point of a long series of trial and error with non-teflon coatings, most of which seem to work fine for a month or two and then are non stick at the same level as one might expect from cast iron. I have no idea how much I've spent buying pans a few times a year at $20-50 a pop to replace worn out nonstick over the past 10 years.
I make french toast, omelettes, over easy eggs, and toast. I have never had sticking that you are talking about...
Also, the type of oil you use to season your cast iron cookware is important. You should use flaxseed, grapeseed or avocado oil. Do not use olive oil, because it has an extremely low smoke point. Canola and vegetable/soybean oils are unhealthy.
