This is my opinion and i don't think by any means that its the "right" opinion, it's just how i see the game and how i play it:

Weapon guides are kinda needed since the same weapon class can work completely different depending on the Hunter Style, there's so much deep with the weapon systems and let's all be honest, it's very confusing for the most part, especially in this game (MHGU) where the game expects you to know stuff already about MH - For reference Gajin Hunter is the Go To for MHGU weapon guides, that beautiful perfectly English speaking Japanese boy.

Now for the monsters itself, and this is excluding Deviants cause those are End-Game, and I'll say it again, it's my opinion, the fun part is understanding the moves and learn how to counter / evade them. Things like Kiranico DB site and MHGU DB App are fundamental to prepare for a fight, learning the monster weakness and most vulnerable areas, what it drops and etc, you can read the hunter notes / quest notes (sometimes it gives tips and tricks). This research "work" is super fun for me, not only you get more immersed, but feel like a actually hunter, understanding the beast before hand to work a hunting strategy, what armor to use / weapon / style. Fighting the monster is another part, you need to focus, see how they move / attack / evade / special stuff etc and applying what you previous learned to defeat it. If there is a guide that gives everything to you, this game is nothing more than a extremely repetitive rhythm game, you could enjoy it, but i bet it will get old fast.

NOW!!!! and to help you, you can search on google " mhgu [Enter Monster Name Here] tips" and i'm 99% sure there's a reddit post about how to fight said monster.

PS: sorry if i completely missed this post point :S
