Does there exist a list of all the alternative writing styles/fonts for kana characters?

I’m currently practicing my handwriting of hirigana, and I’m trying to decide on which styles of writing I should use for a few different characters based on what is the most comfortable and neatest in my writing.

I’ve seen alternative styles for many characters. From what I can remember, those include (sorry, I can’t find a decent iOS Japanese keyboard) i, u, e, ki, ke, sa, se, so, chi, na, nu, ne, fu, mu, me, ra, ri, re, and wa. Some only have very slight variations while others more significant.

I’ve been Googling for the last half hour looking for such a list or chart, but none seem to be easily found.
