I just set subscribed to my default and prune my subscriptions. I like some politics, but I get enough from what seeps through in News, so I un-subbed from politics. I will seek out meme communities that are my speed and leave the rest to their own devices. I just take a peek at “all” every once in a while, and I tend to check out links people post in comments that interest me, but for the most part I have my corner of Lemmy more or less how I want it.
