Just use your Bash/zsh to run Bash/zsh scripts: `bash script.sh`.

I was like this when I first started using Fish. I spent some time to learn some different syntax to get away from the POSIX-compliance. Overall, I think the saner syntax of Fish is worth the effort. Now I use the terminal much happier.
Besides, 90% of the time I don't need to follow POSIX-compliant. Many scripts or extensions nowadays support Fish.
For enterprise use, I still stick to Bash/zsh. They're the standard.
