One of my favourite things about The Sims 4 is all the different aspirations and traits you can choose for your sims to give them their own personality. If your sim wants to be famous, the main actor aspiration could be a great option.
Traits that help with the aspiration of the main actor
There are not really any traits that will directly influence your attempts to complete the aspiration of the main actor, but there are some that might make it more fun.
The first is the egocentric trait that comes with The Sims 4 Become Famous. These sims are more likely to want to be famous and since you'll be in the acting career, you'll become famous and you'll want to make sure your sim can handle it all.
You could also choose something like extrovert because as an actor your sim will be constantly surrounded by other sims during their concerts and will also start to be followed by paparazzi. You definitely don't want to be a lonely sim and make them famous.
Aspiration reward for the main actor
When you complete the lead actor aspiration in The Sims 4, you will receive the world famous actor reward trait. This trait says that your sim will "never fail an acting gig - as far as anyone can tell..." which means your sim will be a much better actor and perform better in acting gigs.

Using Fame Points to your advantage
As you level up, you'll start earning things called fame points and you can use these points to earn rewards that will help you become a better actor.
I suggest you get fame advantages in the category of fame advantages for skill and career enhancement. This includes notable, Celebuserum and the most important established name. The established name fame perk makes it so that you don't have to audition for other gigs, which makes it easier for your sim to get the highest paid gigs.
In addition, the established name allows you to skip hair and make-up when you get to your gig, which can be a big suck and is sometimes the reason why sims are unable to complete all their daily duties.
Final thoughts
The Sims 4 is full of all sorts of interesting aspirations for your sims to complete, and with each new expansion pack comes new ones to try. The main actor aspiration was really fun to complete, have you ever tried to complete the main actor aspiration? How did it go? Let me know in the comments!
