Will I need to fix fragmentation after shrinking a database full of only HEAPs?

I have a 1 TB database that contains hundreds of quarterly archive tables and I am looking to drop any table older than 5 financial quarters, which will free up ~600gb of space. To provide an example of what the table architecture looks like: myTable myTable_Q4_21 myTable_Q3_21 myTable2_Q4_21 myTable2_Q3_21 I am wondering if after dropping these tables and shrinking the database to reclaim the newly freed up space if I will need to either ALTER..REBUILD each remaining HEAP table or put a CX on each table and remove them afterwards.
