I joined one mostly for content in my native language for my kids, it’s as good as impossible to find on public trackers. Initially I intended to only use it for that, but I have since abandoned public trackers completely and exclusively use the private tracker now. I don’t find more time or effort intensive at all though, not sure what you expect to do beyond seeding to meet the tracker requiremens, I seed everything I’ve downloaded, so it makes no difference to me and I haven’t noticed any difference whatsoever in effort to use a private tracker compared to a public one.
I’m using one specifically for the Nordic/Scandinavian countries, not sure that’s what you’re looking for.
