Help Me Prepare For Pokemon Home + Gen 8!

[PreparingForHome]

Hi everyone. I am a very new member and after posting this topic, I will be researching how to get started on my goal to obtain every competitively trained pokemon, including event pokemon.

Here is where it gets more complicated:

-My 3DS is NOT hacked and I have not touched it since Sun/Moon came out (so it has not been updated since)
-I have Pokemon X/Y with most of what I want up to that generation (excluding event pokemon)
-I have Pokemon Sun/Moon with almost no gameplay (a few hours in)

And my question:

-Will I be able to hack my 3DS and use PkHex?
-Is there any possible way to hack in "future pokemon" (such as Sword/Shield pokemon) [I have no faith in this actually being a thing, but I thought I might as well ask]
-Is there a PkHex file list of every pokemon already competitively trained or would I need to do all that manually again?
-Is there a PkHex file list of every EVENT/GIFT pokemon as well?

I would love any help I get to helping me (and hopefully others) get started on this goal. Thanks in advanced!

EDIT: I have found where I can obtain different files, although I haven't looked in detail for what I specifically asked, I am sure I can find what I want.

ALSO WOULD LIKE TO NOTE THAT I AM LOOKING FOR LEGIT POKEMON ONLY!

[Hello, it's me!]

Yes, you can hack your 3DS and use PkHex

No, in order to hack in future pokemon ( I.E : sword & shield ), you'll need a hacked switch

Here is a pkhex file that is full of legit competitively trained pokemon 

You can get all the pkhex files for legit EVENT/GIFT pokemon from here and here
