Hi, there are a couple of people doing nice things with Trad on boehm system - Joannie Madden, Lucie Perier more recently, and historically I’m sure someone else can fill in some names.
I wrote a book a couple of years ago “Irish Music on the Silver Flute” which is available from my website or amazon. And some of the Irish flute books touch on silver flute like Grey Larsens great book. If you check out my YouTube (Philippe Barnes) for some examples, I’m planning to put up lots more and some technique explanations too.
There are some great resources online for learning wooden flute/irish tunes but my main recommendation would be to find a good teacher even if it’s only for a couple of guidance lessons to set you on the right path. I do offer online lessons, but you have a sea of great options at the moment as most musicians have started offering online tuition - for instance John McSherry has a great patreon for Low Whistle/Pipes and essentially you can adapt any of the techniques for the silver flute
