Is it possible for me to reach the natty limit on a 5x5 and accessories

It's nearly impossible unless you have the genetics I'd say. You'll grow less every day that at some point of doing the same shit you'll basically stop growing. You are better with doing 5×5 for a few months and 4×15 (for example) for a few more before going back to 5×5.
Just basing on my experience of only achieving noob gains on a strength program no matter how much weight I kept adding and experience a nice growth phase when I switched to high reps

No, eventually you will stall and need weekly programming rather than daily. These types of routines are slower in progression than beginner routines so as long as you can handle the linear routines you want to stay on them.

5x5 isn't a routine its just a rep range, but yes you can. When you max out you play around with the loading and rep scheme to pretend some progress is being made then end up adding 5 lbs to your max the next year like powerlifters do.
