Excel 365 for Windows and now Excel 365 for Mac and Mobile apps have a long overdue improvement to its drop-down list selector. At long last we have AutoComplete or Search for pull-down lists.
You’ll be able to type a search into the drop-down list so Excel can show all the matching results. For example, type CO to reduce a long list of companies to one with only those two letters.

Who gets it?
AutoComplete for dropdown lists was originally just in Excel 365 for Windows during 2022.
In late September 2023 it was added to Excel 365 for Mac plus Excel Mobile for Apple iPhone, iPad and Android.
