How can I put my home directory on a different partition?
I want /home to be on a different partition than the rest of my files. How can I do this?

Suppose you currently use the partition /dev/sda1 for everything, and you create a new partition /dev/sda2 to use for /home. It doesn't matter if the partition is on a different physical drive, same drive, LVM, etc.
All you have to do is move your files to the new partition, and make sure it is mounted at /home automatically during boot.
The automount configuration is in /etc/fstab (https://wiki.archlinux.org/title/Fstab). In short, for home you can use something like:
UUID=abcd1234 /home ext4 rw,relatime 0 2
Note that it's better to specify the partition with UUID. I am giving examples as /dev/sda* for simplicity.
You should test this with a dummy folder, like /home-test, so that if you make a mistake and it fails to mount you don't end up with a broken homedir.
