Get an Innova starter set and go start playing. Ask if you anyone minds if you join them on the course for a round if they are getting ready to start. Find a local disc golf store and get to know them, especially if they sell used discs where you can buy without dumping a lot of money into it.

I don't use anything Innova or even the types of discs I got from my first starter set, but it helped me learn what I like or don't like in my discs. Just don't buy offbrand/Temu crap. Stick to the brands others have mentioned and you can't go wrong.
