My view is that if you're going to pay for tuition then for a hands on skill like photography you don't want an online course. You want an in-person one with the tutor there with you at the time to help guide you through things. You will learn a lot more and typically a lot faster and because its help in the moment you'll avoid starting bad habits that will later prove to be a nightmare to fix.
There's also context; a lot of advice works but only in a specific context that is often unmentioned; thus its easy to take simple key advice in words, but lack the adaptability to change your method based on different situations. Again its all things that in the real world you'll pick up from a teacher that are invisible to those online.
Online is great for learning theory; for putting structure to theory and also learning editing (since there are ways to share screen views and work on the same project in photoshop and the like). But for hands on stuff I'd say look for either a class or a private lesson if you are going to pay. The rest I would say get some good books and read through them - books often put more structure and workflow into things in an ordered manner than the internet. The internet free resources are great; but more easily applied to specific methods/concepts within a workflow whilst presentation of workflows is generally poorer .
