I should haven't have added that part about "unless actually family."  The US government does not care at all what Cuban visa you have (tourist or family or other). They only care that your visit falls under one of the categories authorized to travel to Cuba. Since you have family in Cuba (and not just a fiancé) then you are fine. You only need a family visa if you think it is necessary for the Cuban authorities.

It seems like the US Embassy in Havana will be transferring immigrant visa requests to the Embassy in Bogota, Colombia.  No official statement has been made but this article was posted:

I have never heard of the petitioner not being allowed in the interview in Cuba. I think it is really important for you to be there if you have the means to do so.

I agree with other posters who have stressed the importance of gathering as much evidence as possible between now and the interview. Even if your fiancé does not have access to a computer, he has access to internet-- he just has to pay for it. He can open up a nauta account (so that he can send emails on his phone) or a correosdecuba account. When my now husband was in Cuba, he would wait up to two hours a day to write me an email at an internet "café." Since he didn't have a lot of money, I would send him money so that he could use the internet. Given that the internet is becoming more widely accessible in Cuba, I don't think the US Embassy will be that understanding when it comes to lack of emails/text messages.

You do not need to translate anything into Spanish. The I-129F is only for US authorities and so you only need to submit the paperwork in English.

They did keep his passport. After they interviewed us, they told us that he was initially approved but that they needed a copy of his CV. He brought his CV they next day and they told him to check back in a week. When he went a week later, that is when they told him that the case had to undergo further AP.
Did they give you any indication as to why or did they request additional information?
