If you want to mess around with scripting instead of an editor I would recommend Awk- it works great for CSV files and is really powerful. Usually you can use -F,
to separate using commas, but for full CSV support (with potential quoted commas) you need to use something like -vFPAT='[^,]*|"[^"]*"'
(which isn’t POSIX compliant but works with gawk)
I alternate between helix and vim depending on the task, and their key bindings are kind of opposite from each other in a lot of ways. I’ve found that switching back and forth has kept me on my toes a bit and I don’t feel as locked in to one editor as I did with vim before trying helix.
I would also try getting used to the defaults or a minimal config, which is also a good way to feel at home in the editor regardless of the system
