Good luck.

I'd recommend finding a MOOC course that covers some of the fundamentals of computer science to make sure you have a really solid grasp of the fundamentals - the whys and how's etc. Data structures, algorithms, networking, databases, design paradigms (so Object orientated Vs functional Vs whatever), testing etc. If they use multiple programming languages in different classes then all the better as I think learning more than one makes it easier to grasp the principles at a more theoretical/abstract level and not just how language foo does it and you'll find your favourite language(s) eventually in your own time so don't give up if the class is in a language you don't know/like.

It's tempting to use AI - I'd recommend you think of it as a knowledgeable friend who you can ask questions - is there a better way to do this/what alternatives are there? What does this function do? Why does this code do this and not that etc etc. You won't learn if it just implements for you, but as a learning companion you can bounce ideas off of or help you out of a rut etc it is great.

It is tempting to concentrate on like a React Bootcamp or whatever to get "practical skills" to start going off and building things, but I think that is like the difference of being the person who is paid to only assemble flat pack furniture following instructions vs the person who is paid to design the flat pack furniture and all the smart little fittings and how it all goes together and will it be strong enough and fit in the box and meet the price point and look like what the designer wanted it to look like and so on.

Finally, don't worry about writing "bad code" or bugs. We all do it from time to time and no one is perfect.
