This may not be correct, but my impression is that with 一斉, it's multiple "copies" of an action happening at the same time such that it really only feels like one action.
一斉メール → Sending one email to multiple recipients at the same time
選挙の開票は全国一斉に行われる → Ballot counting will begin simultaneously [at the same time] throughout the country.
So even ...
I am wondering if there is any nuance or difference between them ?
Yes, there is. I'll try to explain my opinion.
I am also wondering if there is some politeness attached to it ?

Timing is not important compared to 同時に

The word "一斉" is used when a lot of people do something at the same time.

As you may know, native Japanese words are commonly called 大和言葉 (Yamato kotoba), so I searched for “性交する 大和言葉” and came across this page which reviews a book “Speaking Yamato Japanese ...
I feel like this question is lacking a super detailed answer, so I'm going to give an excruciatingly detailed breakdown of various kanji thresholds.
1500ish: This is probably the range of kanji that the average person remembers how to actually handwrite directly from memory.
2135: This is the number of jouyou kanji. These are the kanji that are required to ...
