I would recommend The Pilot's videos where he reviews every ship in a very entertaining way. There are definitely other ship review videos out there but I find myself just watching his videos for the entertainment.
Hawkes Gaming is also another great channel for guides and information about Elite Dangerous. Definitely a good creator for people wanting to learn different play styles. Also has a good ship review video which is how I stumbled across him.
Lastly I'd recommend Mattius if you're into the mysteries and unsolved parts of Elite Dangerous. Goes into a lot of different theories and lays out any evidence there has been over the years. Has a few videos on Raxxla theories which I find interesting but have little hope for actually being found.
