Answer 1

The Best and Simple way to solve above is

STRING_SPLIT

A table-valued function that splits a string into rows of substrings, based on a specified separator character.

CROSS APPLY

returns only rows from the outer table that produce a result set from the table-valued function. It other words, result of CROSS APPLY doesn't contain any row of left side table expression for which no result is obtained from right side table expression. CROSS APPLY work as a row by row INNER JOIN
