It's good to replace multiple sed processes with a single one using multiple -e parameters.

It's good to use [:alnum:] instead of [^a-zA-Z0-9].

It's good to use tr "[:upper:]" "[:lower:]" instead of tr A-Z a-z as a matter of principle for the goal of lowercasing input. To know that tr A-Z a-z is good enough requires verifying what comes before in the pipeline, and knowing how iconv works. That's added mental burden.

Putting it together:

iconv -t ascii//TRANSLIT | sed -E -e 's/[^[:alnum:]]+/-/g' -e 's/^-+|-+$//g' | tr '[:upper:]' '[:lower:]'
