If you have a system with long-running leaky browser instances, Alt-SysRq-F is a lifesaver. It calls oom_kill, sacrificing one process to save the rest.
Technically, XZ is just a container that allows for different compression methods inside, much like the Matroska MKV video container. In practice, XZ is modified LZMA.
There is no perfect algorithm for every situation, so I'll attempt to summarize.
Gzip/zlib is best when speed and support are the primary concerns
Bzip2 was largely phased out and replaced by XZ (LZMA) a decade ago
XZ (LZMA) will likely give you the best compression, with high CPU and RAM usage
Zstd is... really good, and the numerous compression levels offer great flexibility
The chart below, which was sourced from this blog post, offers a nice visual comparison.
Another option is to mount a junction box (like this) outside. Just run the ethernet cable through the wall, instead of the camera's pigtail. This is a more future-proof method as you can change cameras without disrurbing the sealed wall penetration.
