Recommended Fediverse instances? - Divisions by zero

I want to make a button on my site that makes the person surf THE INTERNET, and I’m making a huge list of the most varied stuff you can end up randomly. I want to add Fediverse sites for the person to find at random, I added the flagships of Peertube, Pixelfed, Funkwhale, Bookwyrm, but for Mastodon/Pleroma/MissKey and Lemmy/Mbin/PixelFed I want to direct the person to selected instances… and so far my whole list list is db0, quokkau and kolektiva social for Mastodon :P I really don’t know much of the Fediverse, can you recommend me more cool instances from Mastodon/Pleroma/MissKey and Lemmy/Mbin/PixelFed?
