Seeking a legit caller ID and spam blocker solution

Hi all, through my experience, the third party apps that are supposed to do this a pure trash. I mean true caller was pretty decent, but it was packed with ads and trackers of course and the overbearing permissions that constantly tries hijacking my set SMS and dialer apps.... I don't think using a third party app is the right solution.

I came across an internet protocol called NCID which is network callet ID, which sounds quite interesting, but strangely there is little documentation and virtually no online community discussion about this.

So I'm wondering what are some good caller ID options available? I'm a private person and I like knowing who is calling also, would like to stop spam. I'm sure there's a whole world dedicated to this such stuff, but I can't seem to find the solution. And tips or advice or anything would be great. Thanks
