edit 2: Found a video by “SpaceRex” on the differences between BTRFS and EXT4, super helpful! He explained it quite well…
edit: It seems that there isn’t much difference between btrfs and ext4 aside from additional features of btrfs, which although I might not need right now, there doesn’t seem to be any harm in using btrfs over ext4, so I will be using btrfs.
Which would be better? Fedora shipped with btrfs, does it have any additional features that are good (quick search shows compression, subvolumes, and snapshots as main selling points for btrfs, but are there any downsides?

These days there isn’t really any reason to avoid btrfs. It’s stable, and has a lot of nice features.
I would say, if you want benefit from the features of BTRFS, then go for it. But you have to read a bit what it can do, and use tools and set it up to get the most out of it I think. EXT4 on the other hand is proven and is a setup and forget experience. I chose EXT4 when installing EndeavourOS, because I read a few things about BTRFS that made me think twice and also I don’t need the features too. So, if you don’t know and have to ask the community, then the best would be to us EXT4, unless you know why you want to have BTRFS features.
BTFS snapshots are such a huge improvement and a live saver if you like to tinker on your system. Also great for backups, which you should make. Use snapper and similar tools.
I’d only recommend ext* for spinning hard drives. For ancient slow machines, go with XFS or ReiserFS (if any distro still supports that even).
I would recommend btrfs at this point. I use it for my OS harddrive and I would also use it for my second harddrive except I don’t want to format it, so it’s still running ext4.
Theoretically btrfs runs slower then ext4 but you won’t see it outside of benchmarks. Btrfs can also do integrity checks and healing so your drive (might) last longer, ultimately, that one depends on what exactly is wrong with it.
