こんにちは！
ご質問ありがとうございます。
ご質問について、いくつか言い方が考えられますが、例えば、
I wish there were competitions where students in the humanities could shine, just as students in sports do in competitions like the National High School Baseball Championship tournament.
とすると、『高校野球に代表されるように、スポーツをする生徒が活躍できる、目立つコンテストはあるけれど、文科系（国語や社会など）の生徒が活躍できる、目立つコンテストがあればいいのに。』というようなニュアンスで伝えられます。
参考になれば幸いです。
"I think it would be nice if there were competitions for humanities students to show their abilities like there are for sports."
"I think it would be nice if there were competitions for humanities students to show their abilities like there are for sports."
"I think it would be nice if there were ~”「〜があればいいのに」
"competitions" 「コンテスト」
"for humanities students" 「文科系の生徒のために」
"to show their abilities" 「目立つ」・「出来ることを見せる」
