I pay for Kagi Ultimate, and it does almost none of what OP asked for. The only thing you could say it does is searching curated content from other people they trust - that is fulfilled by the custom lens feature, since they can be shared.

Same here. Paying for Kagi, and I don't ever use Google for search now. No ads, no SEO shilling, I can curate my own search results, and it's fast.

That's a winner for me.
