How to create a unique PC

[Gomezy3k]

We play Pathfinder 1st edition. No 3rd party publications. I am trying to come up with a unique PC. In Herolab there are 40 various classes but 3/4 of them seem to be pretty useless as Player Characters. Arcanist, Enlightened Scholar, Oracle, Inquisitor, just to name a few just do not fit into our games (and seem pretty useless to me). Which pretty much leaves fighter, Rogue (both), cleric, Warpriest, Druid, Paladin, Ranger, Hunter, Magus Sorcerer and Wizard. These are the usual classes we end up playing. So we pretty much

I am trying to run a Witch but everything I wanted her to do, she cannot do: No fortune telling with tarot cards, to make potions I need to take Cauldron at 1st level even though there are Hexes more important that are needed for defense/offense.

It seems like there are only so many ways to create a Rogue or a FIghter or mage or cleric. After you play one for so many times they get boring.

Any suggestions would be helpful.
