Welcome back!

Which aspect of combat do you dislike specifically? RPG combat does usually become a case of 'find the strongest attack and generally spam that' no matter how well polished it is. Some classes/Jobs are more simplified when it comes to abilities though than others, so maybe it's just you need to find the right class or Job for you?

It should be noted early on you're not given every attack and ability in your arsenal at the start, so what you do have it usually over-relied on as a result, which does make things rather dull. But as you level up and gain more abilities you can start to vary your ability roster depending on the situation, and it should go without saying once you unlock Jobs it adds further abilities to the mix.

Also dungeons early on are rather simple as they're designed specifically to help new players ease into the game and combat - later dungeons and trials start to get more technical with special mechanics or aspects that need to be taken into account rather than simply 'tanking and spanking' it.

Either way, don't give up just yet! The beginning of the game is just the tip of the iceberg, there is far more to it than just what the first ten or twenty levels shows.
