I guess your point is that there are too many options. But you have artificially inflated the count as you have made this point. Most of the things you have listed are not applicable (either not used any more, or are not general and were never used to compose full HTML pages). Cut out the ones which are not actively developed and you only have a handful for each language.
Since the problem seems to be that you need someone to choose for you: use Django on Python, use Rails on Ruby, and for each one use the templating that comes with it. If you switch to another framework, use its templating language. If you are advanced enough to use a microframework then you are advanced enough to plug in Jinja2 or whatever it is you really want.
Django, Rails, and Jinja2 have excellent documentation. I can't understand why you would think that PHP's documentation is significantly better.
You get what you pay for on super-cheap hosts who are somehow incompetent to understand Python or Ruby.

And choice is not a bug.
