Now a days i care lots about these three tags Nofollow, Norefferer and Noopener. I was posting blogs to high reputed and DA (80+) websites but i see that some of them are using these three tags with rel=, So i want to know that these types of link will give us some benefits to build online reputation or its worthless. Please share your ideas and suggestions that we should continue with these types of links or search only for blog who is using do follow or at least only nofollow links.

What matters in building back-links is that they look NATURAL. So, the common idea by bad SEO "experts" that you should build ONLY do-follow links, because they "give more SEO benefit" is, of course, a very bad idea, because it makes it obvious to Google that you are building back-links, and so they will rank you less well. So what you need is a natural variety of different back-links. From high DA sites, as you say (20+), and of course, only from pages with content relevant to yours. Do some research into the current percentages of do-follow vs no-follow links, etc. and make sure that yours are similar. You also need to understand link velocity and anchor-text, etc. so your back-links look natural. I explain all these things in my free SEO guide here: https://onlineprofitexperts.com/online-business-starting-your-business-effectively Chris
Three tags means Noopener Noreferrer Nofollow ..... and in link building area only Nofollow is usable .... So according to me about all links are working fine does not matter its do follow or no follow because variety of links will give you natural link building experience as @Chris- saying above and i think he is right.
They are definitely useful. In my experience, I get the best results with a 50/50 split of do-follow & no-follow. What you can avoid like COVID is no-index. No matter how hard you try, your backlink will never be indexed.
