2016 isn't a sequel series from anything - it adapts the Conviction arc and a couple of the arcs after that. Wouldn't recommend it honestly, which is sad because the 2017 series ends with a nice scene that the rest of the series should've looked like.

If you want more Berserk, manga's definitely the best way to go. If you're going through the 97 series anyways, you can just probably jump back into the manga around the point Guts leaves the Band of the Hawk. That point marks where most of the cut material is at, including two whole volumes and some recurring characters that show up throughout the series. I say this because going through the Golden Age arc three times in such a short time can feel repetitive.

I would still recommend reading the Black Swordsman arc (volumes 1-3) at some point. It's a lot clunkier than the rest of the series in some ways, but it's still a decent introduction to the universe.
