From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Systems like DSM from synology have integrity scrubbing to fight bit rot. Run it once a quarter on a 4 drive, and you're protected. Plus, you should be backing up your data, even with RAID.
BTRFS, last I read, had lots of complexity and weird problems. Hopefully, it has improved since then (about 3 years ago).
Btrfs can be a little complex and needs more user-friendly tooling for some of the advanced features to be useful to "laymen", but OP seems technical enough (the fact that he cares about what filesystem he's running in the first place is an indicator of this) that this should not be an issue.
As for "weird problems", the majority of those seems to come down to users using advanced features without RTFM, and users having underlying system issues that cause issues that btrfs catches early and refuses to mount the filesystem as RW, and the users then blame btrfs for the issue.
I don't mind needing to be technical or having to read to do things right. I probably wont really do much fancy things, I just don't want the filesystems dying on me out of nowhere. If they're stable enough for that, that's enough for me. Thanks for the help
The two things I would recommend to any btrfs user is enabling zstd compression and setting up automatic snapshots using snapper or Timeshift. I would personally recommend snapper if you're comfortable with command-line tools, as Timeshift only supports a very specific configuration.
zstd compression is very fast, so if you have a reasonably new CPU you will notice no overhead from it, making it effectively just free extra disk space.
Snapshots require a little bit of reading to understand, particularly because you will want a very specific subvolume layout to sensibly organize them, and distro installation wizards rarely give you such a layout except on distros that support snapshots out of the box, like OpenSUSE.
The Arch wiki page on btrfs is amazingly good, as is their page on snapper if you want to set up snapshots.
