The ideal option is X Premium (formerly Twitter Blue) to optimize reach and visibility. It has features including the ability to post longer tweets and videos, priority replying, and a blue checkmark. X Pro (formerly TweetDeck) is a superior choice for managing several accounts and scheduling posts if you're looking for more sophisticated analytics and capabilities.
if the golden check mark is too expensive, the blue check mark is a good alternative. It still gives you verification, which can help build credibility without breaking the bank
