I would start by taking a look at the ’ Jazz Music Thread’ thread. Lots of good suggestions from forum members on what albums they are playing. You could also check out the ‘Blue Note Records’ label web site.
When in doubt start with Miles Davis ‘Kind of Blue’
A sampling of artists that I have in my CD/NAS collection are: Charles Lloyd, Charles Lloyd & The Marvels, Bill Frisell, Jakob Bro, Andy Sheppard, Anouar Brahem, Avishai Cohen (Trumpet), Avishai Cohen (Bass), Charlie Hayden, Dexter Gordon, Django Bates, Eberhard Weber, Lyle Mays, Elina Duni, Enrico Rava, Freddie Hubbard, Go Go Penguin, Grant Green, Jack DeJohnette, Jan Garbarek, Joe Henderson, Joshua Redman, Keith Bjornstad, Marcin Wasilewski, Mathias Eick, Michele Rabbia, Nik Bartsch, Oliver Nelson, Pat Metheny, Paul Bley, Paul Motian, Quercus, Ralph Towner, Shai Maestro, Stefano Bollani, Bill Evans, Tomasz Stanko, Tord Gustavsen, Trygve Seim, Vanessa Rubin, Wadada Leo Smith, Wayne Horvitz, Wayne Shorter, Wolfgang Muthspiel, Yellowjackets, Zakir Hussain, Ziv Ravitz.
Lots of different types of Jazz and artists to explore. I have been introduced to a large number of artists since joining the forum. The Jazz thread along with the ’ What are you listening to in 2022 and why might anyone be interested" are two great sources for what others are listening to and easy to access artists if you use a streaming service.
Have fun exploring!
