How comfortable are you with mixing batches of fertilizer using a pH/EC meter? What do you know about Coco? My biggest mistakes when I first started using Coco were
Not having quality pH and EC meters
Not understanding that EVERY watering is made of a fertilizer solution
Allowing pots to sit in waste water
I think Coco is super easy and much more forgiving than soil but it takes a good general understanding to not make mistakes. Imo, choosing which medium shouldn't be based on your status as a beginner but on what YOU feel comfortable taking the time to learn and execute. I've never taken much time to learn how to grow in soil but I know infinitely more about hydroponic/soiless systems. I've tried soil several times but because I don't invest the time to learn the results aren't impressive plus it's slower going than hydro.
Can you do soil and Coco? I don't see why not but they are two totally different ways of growing. You can do anything you want but temper your expectations because no matter how much you theoretically know, you don't always know until something goes wrong in the grow, then after you overcome it you grow yourself as a grower.
What are you trying to accomplish growing autos compared to photos?
I used to do autos but I lacked the space and mistakenly believed the hype that autos were "easier". I have the space now, I prefer taking clones and buying seeds only on occasion, I prefer the consistency of a clone over a seed. I prefer having control over flowering because if I make a mistake or something unfortunate occurs, I can veg long, prune more, etc. because I'm not in a timed clock compared to autos.
Everything is preference plus understanding - one isn't better than the other unless you're doing this commercially. You're just starting out though, I say experiment and see what works for you. I would never grow autos consistently or grow in soil but I appreciate the degree of control/growth/speed that Coco affords me and the consistency that clones of photoperiods provide. Like I said, I've done both ways so I know what I like and will invest my time to do.
