DISCLAIMER: YOU DO YOU. This is a game. Have fun!
Ganyu is not a Melt Headshot Bot, she's not a Diluc slave, she's also not a Cryo MAIN! DPS, definitely not a physical carry, but much more than just a "support".

If you're still on the fence about pulling for her and you're not sure what you can expect from her and what her IDEAL role is, then let's take a second and discuss that BEFORE you spend your Primos/money on something that's not gonna live up to your expectations later on.
Ganyu has a very well defined niche, and that is as an EXCELLENT, STELLAR, PHENOMENAL SUB DPS in a DOUBLE CRYO comp, with ANOTHER, dedicated, Cryo MAIN! DPS to go with (spoiler: Ayaka).
She's not made for Melt or Superconduct comps, but for Permafreeze comps, she synergizes with the Cryo Resonance (also makes it so that you don't need to build ER on her and can go pure dmg instead), and benefits from the new Cryo set, which is all about Permafreeze.
Ideal Setup:
Ayaka, Ganyu, Xingqiu, Flex.
In the end, you need to have fun, please have fun, if you don't have fun, take a break! Good luck pulling for Ganyu!
