New Player 30 Hours In: Bundle Purchase Question

Hi, my new friend got me into Warframe and I have been loving it. It seems to have come at the perfect time in my life and is my first MMO. I am 30 hours in and can see myself playing this game for hundreds of hours. I just have a couple questions that ultimately end in if a player like me should buy anything from the shop:

1. What do most players find fun in the end game?

2. What’s the most fun to collect in Warframe (Warframes, Skins, guns, etc.)?

3. What are the goals most players have?

Ultimately, I’m the type of player that likes to try a little bit of everything. When I get bored, I switch to a new thing and grind it out. I’ve read that everything can be unlocked but that weapon and Warframe slots are what I should spend my platinum on. I’m the type of person that would never want to sell a Warframe unless I got a prime version of it. Weapons i would be ok with selling but ideally, I would like to keep them.

Would someone like me benefit from buying the Styanax Prime Access packs or another bundle? Or is it still recommended to hold off? What would you buy with your current Warframe knowledge as a new player (if anything)?
