Thank you for all the ideas and thoughts on this. I understand that fundamental analysis is required to estimate the future development of a coin. However, this very analysis costs time. And I want to at least reduce the list of candidates.

Top 100-300 is a good idea. But that is the whole point: just a few months ago completely new and unknown coins have stormed the top 100-300. Where were these coins before? For example: https://www.coingecko.com/en/coins/bakeryswap - 47x since 7th Feb.
