Here's a couple more jrpgs I really like that has a more modern/futuristic aesthetic
Phantasy Star 4 is a nice gem from the Genesis. Sega consoles didn't have a big jrpg presence, so it's nice that one of the few on it are really good.
It has cyborgs, a decent story, and a cool feature called Macro. Usually in an rpg, your team attacks in accordance to their speed stat, but with macro you can set up your move order. This allows you to buff a party member before a big attack even if they're a speedy boi, or lets you insta heal a member. It's a cool system that lets you set up a bunch of macro sets for any situation you may be in. It's not too hard, but it does have that classic jrpg difficulty that requires some grinding. It's not a lot of grinding for the rpgs of the time.
The music is hit or miss, but it does utilize the Genesis sound chip to its full extent.
I wouldn't recommend playing the other games because they're boring, slow (literally, it feels like your wading through a swamp), and have tons of grinding.
Star Ocean 2 was the last game released on the SNES, and as such, makes full use of the console. It's not turn based, it's more of an arpg. You can switch between your party members to combo abilities or just avoid using characters you don't like.
It has an extensive crafting system, which was new for jrpgs when it came out.
It's basically a star Star Trek fanfic where your character ends up on a primitive planet, and you have to try to avoid intervening and introducing technology to civilizations, but you end up doing it anyway (in true Trek fashion).
I haven't played the first one, but I did play the third one and liked it a lot. It's a watered down version of 2 with a God awful twist ending, but I like the aesthetics of the ships and other areas. Don't play 4 (the MC is literally named Edge Maverick) or 5 (big titty goth girl > enjoyable gameplay) because they're retarded.
SMT is the most popular of these games, and it's usually regarded as the hardcore jrpg series. They're all pretty good, but I would play Nocturne if you want to start with one. It recently got an hd port, so it's also the most accessible right now.
It's essentially Pokemon for people who like gnosticism. Music is great, you get multiple routes for endings, but requires grinding. You either need to level up for a boss or go and collect the right Pokemon to counter it.
Never make your main character use magic, you have your Pokemon for that.
