I had found myself reinstalling and reconfiguring a lot of the same things over and over while distro hopping, so I came up with a bash script with some of the most common configuration changes and such. As an example, here is my Fedora post=install script:
script
#!/usr/bin/env bash
# remove all permission restrictions from current directory
#sudo chmod -R a+rwX .
sudo hostnamectl set-hostname [redacted]
# prompt for ssh password to use later
if [[ $1 == "" ]]; then
read -p "Enter ssh password: " ssh_pass
else
ssh_pass=$1
fi
# default dnf prompts to 'y'
sudo sh -c "echo 'defaultyes=True' >> /etc/dnf/dnf.conf"
# install packages that are needed to add repos and other packages
sudo dnf up -y && sudo dnf in curl flatpak wget -y
#add repos

Note that I used [redacted] here in places for anonymity reasons. This could give you a decent starting point to do something similar.
