Ideally you should learn through a good teacher/tutor, they should inform you common variations etc.

I am not a learner so I can't really point you to learner resources. But I can suggest:

• Some wikipeida pages are in Cantonese language, you can read them for practising
• Visit some Cantonese-based forums so you can observe how people write cantonese casually

Keep posting questions to Cantonese communities on Lemmy. Many people are willing to help.
