FF7 Remake is good for a modern experience and you can change the combat playstyle.

FF14 is a really solid game with very high highs, but is incredibly long and has the MMO aspect, though they have since made the game's story and all main dungeons entirely playable single-player, if you want to play alone. Shadowbringers is one of the greatest stories I've experienced in gaming.

FF7 is the favorite for a reason, but it doesn't hold up as well today. FF6 is also a hugely popular fan favorite, and is the last of the SNES era graphics.

My advice - start with one of those. FF4 and FF9 are a solid choices too.
