Use 「最終」 mainly as a prefix in compounds like 「最終回」 or for the last train of the day. In everyday speech 「最後」 is the default for 'last', 「終わり」 for something ending, 「結末」 for a story's outcome, 「終点」 for a terminus, 「終盤」 for the closing stage of a match, and 「最期」 or 「末期」 for life's final moments. Casual loanwords such as 「ラスト」 and 「エンディング」 suit relaxed talk, while written options like 「終局」, 「終結」 and 「閉幕」 belong to formal prose. For 'first', turn to 「最初」 or 「始め」.
