Ultimately what isn't being said here is: The level of power your character would wield, is beyond the level norm of the RP community on RPC at the very least. This is going to be one of those situations where while the story is interesting, and I totally understand a want to not have to scrap it, you will need to find a good group to fit in with to make it work. A group that doesn't necessarily stick to the lore norms generally accepted.
This is not a chastisement sort of deal, more of a way to inform you that you will probably need to dial it back somewhat to get a good fit if you want regular "meet on the street or at events RP". Unfortunately, compared to other MMOs with similar RP capability to FFXIV, those worlds were set up to a level of power where you could easily be a master of something and still be relevant to everyone else, whereas in FFXIV the lore and devs have set things up in a way that only certain people and groups have the sort of power you have included into your story. That mindset often deters people from staying here as they want to explore higher ability for their character, but I encourage you to stay!
My best help besides the info above? Some of it has been said.
~Choose one or two jobs to have ability in.
Â
 -Probably not WHM as that is hard to get into, maybe if you want to keep healing  magic, do CNJ as stated above.
 -To be an IC bard, one doesn't have to be an archer, though having ability in  archery would be something a Dragoon or a Dark Knight could very well have. I  would say choose one of these you like and stick with that, if you want to tell  stories or sing songs as a bard IC, then do that.
 -You do not have to switch jobs in content at all, I would let that sink into to  help you choose what you think would be best for your character ICly to have.
Best bet? Try something a little more minimal for your back story. I am not saying take all the juicy bits, but look at your character from the perspective of emotional development in our shared world, rather than the gaining of power. There are lots of stories still to be told in our world, research a little more, get a feel for how things are, then proceed with that. There are people here who can help you should you have more questions!
~Don't leave! Stay, we want more RPers! Good Luck!
