There is a subreddit /ValorantCompetitive. You can follow that sub and vlr. These are the two that I know off. Also you can follow the players/people on X, involved with the valorant esports scene. There are tons of vods on youtube alone. You can follow some of the creators like Sliggy, FNS, etc. There are analysts as well like Teets, Thinking Man's Valorant.
Also, there are some fantastic channels that actually make banger documentaries. Some of them are Commend, snstry, etc.
Then there is Plat Chat and VOD father where casters and analysts come together in a podcast and discuss about the game and the matches played. You can also check out the channels controlled by the teams/orgs for further researches..

This is actually a great time for you to research because it masters season already.

I personally watch a lot of FNS stream because:

1. His analysis are much more relevant because he himself used to be a player.
2. He is extremely intelligent and does fantastic analysis
3. He is super funny, and indian. That's why he's the GOAT

OOOOO!
