要搞清楚你问题中不同用法的关键是理解 exciting 和 excited 的差别.
简单地区分就是主动(-ing)和被动(-ed):用 -ing 表达“让人兴奋”,而用 -ed 来表达(人受到某种刺激而)“兴奋”.例:
It's exciting that he has passed the exam.(让人兴奋:“他考过了”这件事让人兴奋.此句中的 -ing 实际上是形容词,而逻辑主语是 that 从句.这件事才能让人兴奋.)
He is excited that he has passed the exam.(He 兴奋了:为什么兴奋?因为He 考过了.此句中的 -ed 也是形容词,但是一个含被动意思的形容词.事情不会“激动/兴奋”,人才会.所以此句中的主语是人:He.that从句做句子表语(形容词 excited)的补足语.)
同样的道理,在有 for sb.to do sth 的句型中,只可能有 It's exciting for sb.to do sth.而不可能有 It's excited for sb.to do sth.

应该为It‘s exciting that ……令人激动的是……(主语为某事令人激动)It‘s excited 、 (主语为某人为***感到激动)
It’s excited/excitng for sb to do sth. 同理 主语不同用法也不同
