There's a lot of opinions around surfing these boats, especially now that there are more options than ever.
I'm with
@Scottintexas as to my opinion in the Thrust Vector Wakes. I would not but them for the wakesurfing ability. They have their own ladder attachment but I am not a fan of how they are suggesting people run their ballast. It's very rear heavy... Anyway, I don't mean to bash. They have their benefits, I guess.
The WakeBooster is designed to fit the 2017+ 21' boats. You could have your own fabricated or I've seen a member here
@3 green tornados modify one to fit his 2015 212x by relocating the mounting holes. It was a great success.
I personally run the wake wedge on my '16 AR240. I've added ballast in the stock locations along with the custom swim deck bag from Gantlin. The combination is phenomenal in my opinion. I'd argue it's the best, although I'll admit I've not invested in or tried the others. I've seen and heard several comparisons. My experience with the wake wedge may be unique in the sense I happen to be a watersports dealer. As such I've been able to ride numerous boards behind my boat and Gantlin setup has allowed me to be successful riding ropeless and playing in every one. I'm 5'10' 195lbs and I have my choice if boards from 4'4" and up. It's awesome! Message me if you're in the market for a board and I'll give you my best recommendation and a juicy discount.
Best gear behind any boat for wakeboarding, wakesurfing, wakefoil, wakesurffoil and SUP. Life is better behind a boat with Transom Watersports.

Here's the Gantlin site which you've likely already found.
I don't run any steering enhancements, but if I did, I'd likely go with the Cobra Jet for the added high speed handling.
