Anything you can put on Aeris to make her a better fighter, you could instead put on anyone else and get an even better result.
I'm very interested in hearing how she can be made into a good fighter. If she's not going to use magic, you'd be better off with just about anyone else instead of her, which makes her a mage/support character, not a balanced all-purpose character.
First off you steal the Striking staff from Eligor in the train graveyard, it has 0=0 0 0 materia slots and an attack of 32 (completely unrivaled until you steal the Hardedge in the Shinra Tower which has the same attack) This weapon can also be bought in Gongaga, but you can replace it in the Gold Saucer with the Umbrella, which has an attack of 58, then, if you fancy a challenge on the demons gate, you can equip her with the princess guard and kill off 1 or 2 other characters and her attack power doubles or triples. As for low HP? Make her status Sadness and she takes 30% less damage, or give her the long range materia, or live dangerously and put her in fury status and give her the cover materia and abuse her Fury Brand limit, any way you look at it, Aerith enables an extra limit from Cloud and your second which is more then enough warrant her use even if you don't like her.
Any argument you can come up with as a reason to not use her can be countered by Fury Brand.
I should also mention that I assume you are talking about boss fights, because standard fights are over to quickly for there to be any risk or reason to use strategy.
