Naruto first part?

I watched Naruto as a child and would now like to watch it again. There are several Naruto films and series on Netflix. I somehow have no plan as to which part is the first and the whole thing was pretty confusing online. Can someone tell me what the first part is exactly called?

The first part is actually just called "Naruto"

Are the films related to the series or is it not confusing when I watch the films while I'm still watching the series?

Don't you have to do the films have nothing to do with the series?

Almost all films have to do with the actual plot.

Only the following are relevant:

"The Last: Naruto the Movie", which takes place after "Naruto Shippūden" and before "Boruto - Naruto Next Generation".

And "Boruto: Naruto the Movie" which shows the beginning of Boruto. This is also shown again in the »Boruto - Naruto Next Generation« series.
