Hi, I have started trying to learn the breath of the wild speedrun and I'm unsure what category I want to go with. However, I'm going to start with great plateau any% runs at first to familiarize myself with the game and its tech outside of wind bombs. I can do stasis shrine clip and shrine of resurrection clip fairly consistently and can fall damage cancel, but I haven't practiced the BTBs or stasis launches enough. If I continue to practice at least 2-3 hours a day, when can I expect to start my first run?

You can do your first run whenever you feel like doing your first run. There’s no magical formula that says “if you practice x hours for y days, then you can do you first run in z days”. Some people practice a lot before doing runs, others barely practice at all, it’s entirely up to each runner when they feel comfortable enough to do their first run.

I would also recommend joining the discord, on the sidebar, and asking any questions that you might have

I second to the Bromie. Discord is one of the best places to go for Zelda BOTW speedrunning. I’m also fairly new to the scene and everyone is super kind and welcoming.
