Once you've picked up the basics, you'll know what you want to try next. I still haven't done shaped clothes & toys; I've stuck with flat things but have got experimental with stitch patterns & different types of yarn. Everyone's different. I've even started inventing my own patterns.
Beware of fluffy yarns, as they're horrible/impossible to unpick.
I, too, found Bella Coco very good: I followed her video for the Virus Shawl & it was spot on.
Ravelry.com is great for many things: free & pay designs, yarn info & a very helpful forum.
Pinterest is useful for seeing what other people have made from yarns I've been thinking of using, & for links to stitch patterns.
It's all about learning. Some things which seemed impossible at first have resolved themselves, e.g. I couldn't understand crochet charts but now dislike designs which don't give them. And patterns which seem difficult can suddenly imprint themselves in your brain & you're crocheting away without looking at the instructions.
Enjoy your crochet!
