I would caution going about typing yourself relating to behavior. I would say, types show tendencies, but not behavior. What I mean is, behavior is only superficial representations of what is occurring beneath the surface. You can tie this behavior with this function or that, but the problem is, that same behavior can also stem from say, another function. Throw in motivation, life experience, Enneagram type, whether someone is in a healthy state or not, etc. and you're left picking at behaviors that may not even be tied to a function or type anymore. I say tendencies though, because of the given stacking you will see some patterns start to emerge from individuals of that type. It's like trying to find universal morality and weeding through cultural subjectivity and relativity. It's not clear cut.
But to answer your question, I could go on and on but one thing I will point out as a tendency I see, is relating to the stereotype that ENFPs are flighty, scattered, and indecisive. If you look at all three, they all float around Ne as the root cause. But why? Well because for Ne doms, the Ne process is such a mental stimulation and "high" that there is a bias and natural inclination to stay there longer than other types. Ne is seeing many different possibilities and not being fixed to one decision, that's the job of the following judging function, Fi or Ti. So, understanding that process and knowing the whats and whys of it, brings one to the understanding of just where those stereotypes emerge from. They are stereotypes though, so in reality, they most likely aren't nearly as exaggerated and prevalent as the stereotype would have you believe.
But in figuring out your type, I recommend grappling with the functions, understand them in a way that makes sense to YOU. That's very important. I see people rehashing the same function descriptions every which way, and I wonder if they even know what they're talking about. That's only my perception of course. Then, do some self reflection and try to pinpoint the whys of what you do. Ask yourself what truly guides your decisions and thoughts. Do you tend to place judgement on things immediately? Or do you come to those decisions a bit later? Are those judgements hard-lined? Or flexible?
Sounds like an arduous process, and it can be if you don't tend to reflect on things normally. It's the same as not running the disk defragment process on an old pc regularly, your computer just becomes cluttered.
But if you just want some more quick and easy, I wouldn't blame you. Me, or any of the ENFPs on the forum could give you more tendencies to look out for to help you out. I'm just stopping myself now to prevent this post from going on any longer, but I could give you more. I don't consider myself an ENFP authority though, so I'd cross reference with other members on the forum as well
Good luck!
