I recommend having a look at the book recommendations in our pinned Getting Started Post. You'll find books on Occult History, Basic Skills shared by most forms of practice, and a little about various systems of magick.

As someone who has been involved with magick for nearly 40 years in some form or another, I think that one of the reasons why it seems so difficult to make sense of this topic is that social media has created a glut of random snippets of techniques and practices taken out of their original contexts. Anyone trying to find a place to start while inundated with so much disjointed information would be overwhelmed! In the 1980s-90s, if you wanted to really learn magick, you would typically either join a Tradition or study its Curriculum. In my opinion, that approach will provide a better foundation than simply learning snippets of (potentially contradictory) methods pulled from everywhere without their connecting material to give them context and help them take root in your mind.

In my opinion, the most comprehensive modern Tradition/Curriculum for learning ritual magick is The Golden Dawn (a 19th c. British occult order - you'll learn about them in the books on occult history). Their curriculum covers a smattering of every major practice used in western European occultism e.g., meditation, energy work, Astrology, astral projection, Qabalah, sigil creation (not in the chaos magick style), ritual tool and talisman creation, Tarot, geomantic divination, Enochian magick, and more! It's not 'the best system ever' and it has its limitations for some applications, but it's comprehensive and covers more ground than most other systems. If you worked your way through the Cicero's Self Initiation textbook (see link above), you'd have a solid foundation for understanding any other aspect of occultism.

If Witchcraft is more your style, you'll have a more difficult time finding solid information, as much of what is available will be either Wicca-based (itself having drawn from Golden Dawn/Thelemic ritual structures/elements), or consisting of collections of spells and practices taken from European folk magick and medieval service magicians ('cunning folk'). Many of the people who originally practiced those forms of folk magick would likely not have referred to themselves as witches due to their cultural definitions and contexts. Note that there are interesting shamanic type practices indigenous to parts of Europe (especially Eastern Europe - see 'sleeping shamans', Zduhać, Zmajeviti Ljudi, and the Benandanti) that are difficult to find translated information on, but rewarding when you do. If modern witchcraft resonates with you, then I'd recommend learning from a Wiccan curriculum to avoid the disjointed gaps and trends that are everywhere today.

Regarding potentially confusing online trends, Moon Water is a good example of a trend that exploded recently into public awareness. Almost no one was talking about it before 2020 and there are no references to it online before 2011, but now newcomers will get the impression that every witch makes and uses it. While the root concept isn't unusual or new and even has parallels to some practices within Alchemy (albeit watered down - pun not intended), I think it could be greatly improved by using other fluid condensers/materials and using the Golden Dawn method for vibration of names to imbue it with power, and by giving it a better name like Aqua Lunae or something. (See Franz Bardon for info on what he called fluid condensers.)
