I'm self-taught too, and I remember kinda hitting a wall of "where do I go from here?" around the same point you're at. It does sound like you're into the intermediate-type of moves if you can do a butterfly and cross ankle release, and if you were taking studio classes they would probably say that you're a solid intermediate just because you can invert at all. Take a look at Fleur's post "Am I Ready For an Inversion?" - there's a lot of criteria in there!
I learned really fast so I'm trying to remember what order I learned in... If you can do a butterfly, go ahead and try to work on the extended. If you can do a cross ankle release, can you do the cross knee? (I did cross knee first) If you're confident with your cross ankle release you could try a bow/bridge (try it close to the ground first, like with your hands resting on the floor). From Gemini and Scorpio you can try an inverted thigh hold. Flatline Scorpio is another one you could do - it's my favorite transition out of the butterfly. There are also the plank and advanced plank, layback, wrist sit... the list goes on. Learning to combo between the moves is another great way to build up strength and learn more about how your body is gripping the pole so you can go on to other moves, too.
Spins are fun and a bit less dangerous, too. 😜
Have you looked at Wikipole? I used that site to become familiar with the names of the moves so when I watched the videos I could define them better. When you're just sitting there without knowing what to look for it's just like "Oh I want to try that one leg thing." Also you learn what parts are the moves themselves and what parts are the transitions - makes it easier to know what to work on in smaller pieces before you try the whole thing. This site is also a great resource for stuff like that, too.
Learning moves from just pictures and watching videos is generally not recommended, but that's kinda what us self-taught people have to do. It's learning to recognize what you're not ready for that's the hard part. When I watch videos, I know right off the bat that cartwheel and handspring mounts, ayshas, straight edges, jade splits, etc. are all over my head right now. I look at moves that I already know how to do and watch what the other dancers do in between them. It's just learning what body parts are doing the gripping and what kind of strength is involved, and figuring out if it's something that you can build up to easily from the point that you're at now. Knowing what you can do safely and working on them cautiously is the key. Use mats or pillows and a spotter if at all possible, and definitely do strength training exercises.
There's my 2 cents. Just don't hurt yourself!
