Today I wanted more than 30 choices (asking which country was better to live). but that is a rare case.

I'd be glad if I could automate the answers: wrtite the list in a spreadsheet or word processor and insert it automatically. Less work. (I need spell checking and grammar checking apps before I make a poll.)

A poll with 50 choices can be good in some (rare) cases.
For example the case what @deathcross mentioned in this comment.
