Basically, I want to make one for some multiplayer games out there (along with Stoat communities, or something similar - what do y’all recommend? Bonus if it has voice chat).
What would I need, and how can I set this up safely without having my own network hacked beyond comprehension? I could do it off site from home too if that’s better.
I have a Raspberry Pi 4gb, but also an old DDR3 16gb desktop with a PCI network card available if that’s recommended.

First of all I would recommend you use Piefed instead. Easier to setup and maintain.
But I am not sure exactly what you want that Lemmy/Piefed instance for? As an internal forum of sorts? That can work, but is not really what it was developed for and there are better (non-federated) options.
If you want it to be an actually federated instance then the Rasberry will not cut it. The desktop might, if it has some good SSD storage for the database.
For in game voice-chat the simplest option is a Mumble server. Very low resource use and runs great on a Rasberry like yours. Otherwise you could also try setting up a Movim instance. It has text chat and voice/video calls that should reasonably work as a Discord substitute for small groups. It is also quite low resource and should run fine on that Rasberry.

Do you have a source or benchmarks for the last bullet point?
I am skeptical that optimizations like that wouldn’t already be implemented by postgres.
Edit: Btrfs has the worst performance for databases according to this benchmark.

Are you maybe looking for something like Revolt or Spacebar?
They got a C&D over the name and switched it to Stoat, which OP said they’ve tried before.
I don’t get why they picked Stoat; it’s a terrible name, but it is what it is
Didn’t know that. I agree it is a terrible name, but maybe that’s why it is safe from any cease and desist orders…

Couldn’t you just create the communities on an existing server? Obviously it would be good to not be on the biggest one to help spread out the community, as that’s the point of federation. If it’s on a server with existing users, you’re more likely to get members join as it will show in their local feed.
that’s a good idea as well! might consider that.
How would I do that? I that each and every community had to be manually approved by the server administration
I think it depends on the instance. So check the instance rules that you are considering. Then message the mods and ask, I reckon!

I want to set up a Lemmy server too (currently still deciding between Lemmy and PieFed) to host some basic content that we create at a university group with the public. It’s more like a blog than anything else, at least as envisioned. I’d also like to add some cool features to it like auto-posting (i.e. we have a bot that automatically uploads certain posts).
Disclaimer: I might be talking out of my ass here but this is how I think it works, to the best of my knowledge.
The safest way would be to make an instance that only hosts the communities; it has no users and therefore federates no subscriptions of other communities who’s content you may need to police for stuff like CSAM that isn’t caught right away. You’d only need to monitor and moderate your own communities created on the instance.
I’m not sure but you might need one account to be an admin/ moderator for the communities you create? Just don’t subscribe to any off-instance communities with it and it shouldn’t federate those posts.
Folks on other communities will interact with it via someone from their instance subscribing to it; so discoverability might present an issue.
Just don’t put hacker clothes in front of your computer
