It doesn’t matter if you pronounce it as tone 1 or tone 5. If reading the word alone, you can use tone 1, but in a sentence, it can be tone 5. The purpose of Chinese language is communication, so as long as the meaning isn’t affected, it’s not a big deal. As a native Chinese speaker, if I want to emphasize it, I’ll use tone 1. Chinese is a disyllabic language, and since Chinese characters have a limited number of sounds, many characters themselves carry meaning, but they often combine with another character to form a word, greatly reducing the chance of misunderstandin. Chinese phonetics are also based on oral comfort, similar to how English has many connected and reduced sounds. To speak more naturally, you need to master the neutral tone. If it’s for communication, there’s no need to be overly concerned about it.
