I've played a good bit of FTL and never felt like I knew what I was doing.
I actually noticed recently that it's no longer maintained so I'll have to find another desktop solution.
I've started seeing racist memes from the exploding heads instance on All. I know I can (and have) blocked the communities I've come across from there, but I'd be happier to know that my home instance doesn't create a space for the people seeking out that kind of content. Obviously I'm not in charge here and to my understanding we ideally do things democratically here, so I'm really just hoping to start a conversation.
On fdroid the best I could find was Blockinger which was last updated 9 years ago. It seems to work fine on my phone, but I do wonder if there are any newer projects or improved forks that I can use. Thanks!
On desktop I use Tildes. It's fairly minimalistic in terms of features, but very smooth and attractive UI. It does what I need with no headaches and looks great doing it. Like many others here I use AntennaPod on mobile.
