The caps lock key is definitely using prime real estate on a keyboard for something that doesn't get used often.
I have taken to remapping it to a function key, moving caps lock to function+shift.
Function+tab is mapped to escape, a combination I can easily press with my pinky alone.
This allows me to map a lot of the keys that would require moving my hand to function+[alphanumeric key], function+i is insert, function+u is page up, function+j is page down, function+r is home, function+f is end, and other such combinations.
I use a keyboard that supports QMK, so all of this customization is on the keyboard, but this could probably be done with software running on the computer, like AutoHotKey on Windows.
