SMT and its spin-offs like the Persona series are known for turn-based combat systems that emphasize strategy, exploiting enemy weaknesses, and team composition. Some suggestions:

• Persona: especially Persona 3 onwards offers a mix of life simulation with combat that's similar to SMT.
• Etrian Odyssey: dungeon crawlers where you map out dungeons as you explore.
• Octopath Traveler: "2.5D" art style from Square Enix.
• Digital Devil Saga 1 & 2: spin-offs of the SMT series (have you played them already?).
• The Legend of Heroes: Trails: combat system with positioning on a grid.
• Divinity: Original Sin 2: Western RPG, but its combat system is deeply strategic. You can use the environment and elemental interactions.
• Darkest Dungeon: challenging roguelike that focuses on stress and psychological trauma.
• Fire Emblem: TRPGs where you move units around a battlefield on a grid. The combat is more about positioning.
• Bravely Default and Bravely Second: characters can "Brave" to take multiple actions or "Default" to defend and save actions for later turns.
• Final Fantasy X: You can reorder actions in battle. I always found this annoying but you seem to like it.

These RPGs vary in their execution, but might give you a similar satisfaction to what you've found in the SMT series.

Does it have to be a JRPG? If you want tactics in your turn-based games I recommend looking into cRPGs as the genre originally started as adaptions of tabletop games and has way deeper tactics compared to most JRPGs. Stuff like the Baldur's Gate games, Dragon Age, Wasteland, Divinity: Original Sin 1+2 or Arcanum: Of Steamworks and Magick Obscura are all turn-based or real-time with pause which work similar enough to count. As a plus point most of them allow you to be rather creative in the way you play from stuff like talking an opponent into killing themselves to turning opponents into chicken and letting them bleed out with another skill.

Of course all Atlus games have kind of a similar gamplay, but SMT gams are more challange than most of the others. But with Soulhackers 2, you are about as free with your team as in SMT and is has some challanging enemies you need to prepare youself. But it's about the same as SMT, so let's try to find something new.

Maybe the trails games would be interresting for you. Trails of Cold Steel 1-4 or Trailf of the Sky would be two points to start into the series. Sure you have a party with different kind of strengs like in typical jprg's, but i think the battle system helps a lot if you want to try different kind of strategies on hard bosses. The Trails of Cold steel games are not just turn based games, they have a fighting area you are able to move youself to get near the enemy or get away from the and attack with range attacks. Attack could hit in different areas as well, so you strategy is not just about the skill and attacks you use, but as well about the positioning on the field. Often that helps a lot to overcome enemies. The armor and weapons you equip are also help you do skill your characters very differently. Give a fast character a lot equipment with avoid stat, and this char will probably never been hit again from physical attacks.

A lot jrpg's have it's main party and you limited to their abilites, not like in SMT, so probably a monster catching game (SMT is more or less one as well) would be good. I think the Digimon Cyber Sleuth games would proabably a good recogmondation. Yes it's a Monster Hunting/Farming game you play 3 Digimon at the same time, able ti switch them and all of them heve their elements and atrribute, which gives them advantages and disadvantages over others. I would recommend to play it in hard to get about the difficulty as a SMT game and it could be a fun experience for you.

I'm the mod of a jrpg community, maybe the people there would post more interresting titles, because of haven't play everything.

tri-Ace games have fantastic combat mechanics, imo. Give the original Valkyrie Profile, any Star Ocean (later games have more intricate combat), or Resonance of Fate a spin.
