I can't say much re: peculiarities of direct injection and nitrous, or this car, but in general I probably wouldn't bother with nitrous again.

While it's fun for a bit and the instant boost is like nothing else the cons outweighed the pros for me.

Done right it will cost a good penny, money that can be put toward FI. A barebones kit might look cheap but gauges, automatic bottle opener, and other items add up fast. Refills are annoying. It's illegal for road use and while using it you may attract unwanted attention.

I never got to play with the computerized systems, throttled solenoids, but that's the route I would choose today. Adjustable on the fly, programmable over the rpm range.

A good system should have backups, as well. That adds more cost.
In my case a piece of something jammed a solenoid open. The fuel solenoid, fortunately, or I'd have needed a new engine.
