First “I am” is the translators choice of words to use to translate the Greek “ego eimi”. Whatever their motives it is not the best translation into English, the language we speak. Time is involved and in English it has to be noted. Therefore other translators translate the Greek “ego eimi” to reflect Jesus’ CONTINUEOUS existence, i.e., “I (have) existed”, “I have been” or something similar

That is correct. These are all verbal acrobatics, stretching the meaning by implication. It means continuous existence in John 1:1, but in John 8:58 it simply alludes to pre-existing Moses, but not necessarily that he pre-existed existence or that he is the existence (ho on) itmself. And a simple eimi is translated as "I have been" in John 14:9. So, it is a human choice of words.

Quite simply Jesus was saying he existed before Abraham existed and he obviously existed at the moment he was speaking (the present), action began in the past and continuing into the present. An undefined length of time but clearly more than 50 years or so.

In deed John 14:9 is an example of an action began in the past and continuing into the present, represented by the word “eimi”.
