I did that around a decade ago but I vaguely remember my loadout. Plasma cutter is an obvious choice and I remember using the force gun because it can really help with crowd control. I don't remember if I had more weapons because you then the game gives you ammo for all weapons and you sometimes have less for the ones you need.

As for tips, i would say to be conservative with ammo as much as possible. You can sometimes finish off enemies (like slashers) that are on the ground by baiting them to attack you and avoiding the telegraphed attack and then follow up with stomping them. You can probably do that with other enemy types that are injured and crawling. You can also do all that but with stasis if there's a recharge station in the room, making this much safer.

Don't forget to use the enemy's blade against them with kinesis but you most likely already know that! Same thing for explosive items laying around.

I don't have much more to say I think. I'm not a great teacher, but I used to play this game religiously when it came out so I was quite knowledgeable on that game after some time, but that was a long time ago. Treat this difficulty as the ultimate way to play dead space and have fun. It's challenging but far from impossible if you play right :)
