I don't think you're un-threeish, I just think you're an 2w3 before 3w2.
Twos "need to be needed". They fear not being worthy of love.
Threes seek success and validation. They fear being worthless.
2w3 and 3w2 can seem very similar because honestly those two fears can look synonymous. But it's about roots and coping skills. Give vs take. A two gives incentives to people so they love them. A three
gains incentives, just to prove that they can. Doing one that mean you can't do the other, but the fundamentals of your actions is what determines your enneagram, not your behavior.
Take me for example. I am an 2w3. Yes, I am goal oriented, flashy, and generally aim to ladder climb, but I don't do that because not doing so would make me lesser. My motives are fueled by giving to others. I want to help people and
be needed. My methods of becoming needed are extravagant and over the top, sure, but if they were small scaled and focused, I would be an 2w1.
Slightly off topic, but do not use behavior as a basis of figuring out your enneagram. It's about what motivates and scares you. Are you worried that your ties with people you care about are thinning and that you must fix it? Or do you fear that on the leaderboard of life, you are on the bottom and will be treated accordingly? Questions like these are what you should ask yourself when figuring out your enneatype.
Also look back to what we talked about in DMs on Discord.
Not sure how I feel about this description, but I thought it was worth adding.
The Enneagram Institute on confusing e2 with e3:
Here again, confusion about wing versus dominant type is likely to be the problem. A Two with a One-wing is unlikely to be mistyped as a Three, and a Three with a Four-wing is unlikely to be mistaken for a Two. With the 2w3 and the 3w2, however, personal charm and the desire to be liked and to please others can make these types more difficult to distinguish. Confusion sometimes arises, for instance, because the word "seductive" has often been applied to type Two. But clearly, all types can be seductive in their own way, and Threes can be very seductive indeed. Therefore, it is important to distinguish how these two types "seduce" attention from others. Basically, Twos attempt to get others to like them by doing good things for them–by focusing on the other person. ("How are you feeling this afternoon? You look sad.") Twos give the other person lots of appreciative attention in the hopes of being valued as a friend or intimate by the other. Twos are primarily motivated by the desire to please the other as a way of creating closeness or intimacy–to enhance relationship.
Threes get others to like them by developing the excellence of their own "package." Threes seldom lavish attention on the other; rather, they are trying to be so outstanding and irresistible that the other will want to focus attention on them. And while Threes enjoy the attention, and want relationships, they actually fear intimacy, becoming more uneasy as the relationship becomes closer.
Twos and Threes are different in several other key areas. While Twos can be ambitious, they feel uncomfortable going after their goals directly, feeling that to do so would be too selfish. Threes are extremely goal-driven, and feel they are not living up to their potential if they are not the best at what they do. Twos are openly sentimental and emote easily. Threes tend to be more composed, and to have difficulty accessing their feelings. Twos keep trying to do nice things for others until they lose their patience and blow up when they go to Eight. Threes keep driving themselves to excel until they burn themselves out and become more detached and passive when they go to Nine.
