CRPG's generally not known for amazing combat.

Pathfinder games are probably what you're looking for if you want the more modern Baldur's Gate experience that isn't Baldur's Gate 3.

But I wouldn't say combat is all that much better. More modern, but it's based on a very similar ruleset.

If you're going down that road, You may as well go further back and play all the top rated games in the genre. Neverwinter Nights 2 still holds up decently well, Mask of the Betrayer Expansion is still one of the best story contents for any CRPG ever made. Pillars of Eternity is solid, Tyranny is a very interesting twist on the standard fantasy story from the perspective of the evil side.
