I believe in the June issue, which should come out in May, Practical Photography magazine will be running their Camera School. You sign up, it’s free and there’s no commitment. It would be a good way to get back into it.
Each month (for 6 months) you get the magazine, they explain what you have to do and give you a brief. You submit an image and they will critique it and give you a score - bronze, silver or gold, depending on how well you meet the brief. It’s aimed at beginners and will lead you through the different modes on your camera as well as exploring different genres of photography.
Also, yes YouTube is full of useful videos.
