ansible has a learning curve but will save you a lot of time in long run over bash.

write playbooks rhat target groups of similar hosts instead of a playbook for each distinct host, target specific hosts with -l flag of ansible-playbook.

look into molecule for testing sooner than later. helps you be more confident your plays will work as expected vs running trial and error on a host and getting it into a bad state. i run on bare metal so more important for my workflow not to wipe a folder with a typo, etc.
