Not meant as an authoritative or absolute assessment, but this viewpoint may help you come to terms with the "fragmented" nature of the fediverse and understand why it's the reason we are here (or at least why you would want to be). Lemmy and the fediverse is not "the ultimate aggregation platform" or the new old reddit in any...
Every example you listed involves a corporate entity trying to make money by providing access to the federated network in question. A connection that is 1 to 1 at that, not one to many.
The fediverse isn't that. At the moment, it's communities connecting with other communities generally without commercial interest. As a result communities sidelined by society thrive here. And that includes bigots and vulnerable minorities.
If it ever becomes corporate, the hate groups will be permanently defederated in one form or another by the commercial entities or the vulnerable minorities will move on when it becomes impossible to exist without bigots
And then one or both groups of folk will find new niches and the pattern will repeat
But it does so at the cost of relevance and reach.
And as ever, the vulnerable minorities start and popularise spaces and networks, only to be pushed out by people who have no need of protective mechanisms, those same people then castigating the minorities for not designing the system the way they would prefer
Politics and harassment are one thing, but there are servers that without-a-doubt bad. Some for example literally have "lolicon" in the URL. Not doing that also may or may not invite trouble, depending on your local laws....
So, lemmy is a little different to the rest of the fediverse in that it doesn't have a global timeline or the ability to follow users. All you can do is follow groups on lemmy and kbin instances. For that reason, most of the block lists out there aren't terribly relevant to lemmy as they're designed for blocking microblogging instances that can appear in global feeds of other micro blogging instances.
I watch the fediblock tag, and I maintain an aggressive blocklist on our main blahaj.zone instance, but at this point, it hasn't seemed worth the effort to bring it over to lemmy, given that most of those instances won't touch this instance anyway.
I'm happy to do so if it will bring folk peace of mind however.
Please make sure you have "undetermined" selected in your list of spoken languages in your lemmy settings in addition to any other languages you speak....
A shift of perspective: instances as communities; "communities" as subforums

Suggestion: defederate from known-horrible servers as a precaution
