  I think the question was, what is then considered correct polite past form from Bunpro’s point of view. Surely a simple かった without です would be considered non-polite, so it cannot be that.

  Bunpro article on one hand instructs to use です, on the other hand seems to warn against using it, but then doesn’t give any alternative… Is this caution block even needed, especially at N5 level?

  It is just fine to use です after the past tense of an い adjective. (I double-checked with several of the Japanese teachers of English in my school just to be sure).

  With friends? (Casual) ～かった
  With someone you need/want to be polite to? (Polite)～かったです

  Both 美味しかった and 美味しかったです are perfectly correct (examples) and are used with near equal frequency.

  I’m going to jump in and explain what the line in the write up is talking about and why it is there. This explanation is beyond N5 grammar, so for anyone reading who is currently learning this point you don’t need to worry about the details!

  The use of “い-adjectives” (形容詞) with です is something that has slowly become accepted in the language, as it allows people to speak politely but not pretentiously. Historically, to make the polite form of an い-adjective you actually had to conjugate it and add ございます. I will use non-past examples to keep things simpler, but what is said below applies to the past tense as well:

  おいしい (It is tasty)
  おいしゅうございます (It is tasty (polite))

  Note that this is the source of the below common phrases:

  早い → おはようございます (It is early (polite, respectful))
  ありがたい → ありがとうございます (It is something to be grateful for (polite))

  However, this is a bit long and pretentious/stiff...
