Google's John Mueller said there is no ranking benefit in using different Google Search Console and Google Analytics accounts for each individual web site you manage. The topic came up before, as long as you are not spamming Google - there also is no down side to using the same accounts across multiple web sites.
John Mueller from Google said this on Reddit. The question was "How important if at all is it to run different websites on different search console and analytic accounts?" John Mueller responded "There's no ranking advantage from using separate accounts."
John said this before, saying how agencies have hundreds of accounts in one account and they spend a lot of their time fixing spam issues. But if you are the person spamming, it probably doesn't make much sense for you to have all your spammy sites in one account. Again, this is a topic we covered a few times now.
