You should try fish shell. Great user experience out of the box, including history suggestions.
As an SRE, at my day job I often need to copy/paste commands that are generated from a playbook.
Our playbooks use Bash, and in practice Zsh is compatible. But a co-worker using fish often has to manually modify commands before running, and I'm not about that life.
The problem with fish is mostly the different syntax for setting variables and lack of heredocs. Sometimes the string substitution differences come up too.
You can never completely automate the debugging step: it often requires human judgement to direct the investigation in ways that can't really be expressed in a script.
The friction of the shell comes up not in executing the ops, which we do in fact have heavy automation around, but in all the little pieces of debugging has to happen to tell you what ops need to be done.
(If you get paged and the solution is to skip the debugging step and run a script, then why didn't you automate the script so that you don't get paged in the first place?)
