What is the current scientific consensus regarding the relationship between Eukaryotes and Archaea?

In the traditional 3-domain system, the domains Bacteria, Archaea, and Eukaryota are all distinct from one another, with the latter 2 usually being sister-groups in a clade.

However recent evidence has come to light showing that Eukaryotes might have arose within Archaea, rather than being the sister group to it. More specifically, Eukaryotes might have evolved from the Asgard archaean superphylum.

What is the current consensus towards this issue? Do most evolutionary scientists today still consider Eukaryotes to be the sister group to Archaea? Or is it thought that eukaryotes are archaeans?

Archaea

Today I found out that Archaea are closer to Eukaryotes than Bacteria. This was a huge shock for me since bacteria and Archaea are both classified as Prokaryotes. As well as they both have similar structures Eg. Single celled and plasmids. That they're both essentially "bacteria". How is it that they are closer to Eukaryotes? Archaea doesn't even have mitochondria (from what I know).

I also have known for a bit that Archaea are not pathogens/parasites (at least to humans?). Why is that?

Pathogenic archaea: do they exist?

I find it surprising and amazing that currently there are no pathogenic archaea identified. The review below is from 2003 and since our understanding of the diversity of archaea and the relevance of microbiomes for health and disease has increased significantly. But still, there are no pathogenic archaea identified yet. There are so many archaea in our gut, for example even methanogenes. It is not even clear how we acquire them, as they cannot survive in an oxygenated atmosphere.
Why do you think there are no archae pathogens, there are reports this is due to different vitamin requirements.

ELI5: Why are Bacteria and Archaea both Domains AND Kingdoms?

Why did they make the decision that Domains need to even exist if they don't do anything with the Kingdom taxa for Bacteria and Archaea? It seems to go:

Domain: Bacteria

Kingdom: ...still "Bacteria"...

Phylum: *lots of categories*

Shouldn't all of those phyla actually be kingdoms? It makes things difficult to explain to schoolkids. "So we take big taxa and split them into smaller taxa in order to categorize and organize. We start with three Domains and then have six Kingdoms." "But what about those two being the exact same?" "...Um..."
