You may use

^[^a-zA-Z]+|[^a-zA-Z]+$|(['* -])['* -]+|[^a-zA-Z'* -]

Replace with the backreference to Group 1 value, $1:

s.replace(/^[^a-zA-Z]+|[^a-zA-Z]+$|(['* -])['* -]+|[^a-zA-Z'* -]/g, '$1')

See the regex demo

Details

• ^[^a-zA-Z]+ - one or more chars other than ASCII letters at the start of the string
• | - or
• [^a-zA-Z]+$ - one or more chars other than ASCII letters at the end of the string
• | - or
• (['* -])['* -]+ - a ', *, space or - captured into Group 1 and then 1+ or more of such chars
• | - or
• [^a-zA-Z'* -] - a char other than ASCII letter, ', *, space or -.
