There's not really a cover-all guide for it, as far as I'm aware. But generally, FOmarl is going to cover almost everything if you're not looking to nuke and don't want to rely on rares, considering she gets natural boosts to Resta, Anti, and S/D range. The problem is that her only damage boost is Grants, so she's heavily reliant on her equipment for technique damage outside of that (longer kill times = greater risk of team wipe). Also, her low ATA means that high Hit% is necessary to reliably land Demon's/Hell specials (she can't even use ES Mechgun, which, despite your aversion to reliance on rare weapons, should still be noted - it highlights just how few reliable options she has for Demon's/Hell use, since regular mechguns have reduced specials that are only 33% as effective as usual).
As for FOnewm and FOnewearl, they're...not hugely good from a support perspective without some help from rares (in particular, either Striker of Chao or Tyrell's Parasol). FOnewearl does have boosted Resta/Anti Range, but no other support boost, in addition to only having basic technique boosts and Megid pierce; meaning she does a bit of a worse job of supporting than FOmarl naturally, and basic techniques and piercing Megid are only effective in specific scenarios. FOnewm, on the other hand, has no support technique range boost, but his boosted Gi/Ra technique damage can help to clear out enemies quickly. All that said, FOnewm and FOnewearl both do have high ATA for Forces, meaning that they can more reliably work with Demon's/Hell specials compared to FOmarl (both can even use ES Mechgun for reliable Demon's usage against single targets).
You probably notice that I didn't including Jellen and Zalure, and that's because you absolutely require a rare weapon (namely, Glade Divine) to boost the range for those - no Force has naturally-boosted J/Z range.
