Of course looking at one particular branch of Christianity instead of looking at Christianity as a whole you're going to find a contradiction. Ishibumi has the whole tree of Christianity to choose from. I'm going to go through your points one by one and use quotes to differentiate which point I'm referring to, just a fyi so you don't assume I'm mocking you.

" In the Bible (Hebrew one, specifically) Gabriel is a male"

Gabriel has been portrayed as male and female across all of the religion. You can even see this in the sculptures and paintings of Gabriel who differs incredibly from Michael because unlike Gabriel, Michael is always shown as Masculine. And Gabriel being changed to male was the result of the Catholic church who wanted to keep Mary as the only divine female figure.

" and there's three Archangels in the Christian one, not one"

Wikipedia: "Michael and Gabriel are recognized as archangels in Judaism, Islam and by most Christians. Protestants recognize Gabriel as an angel but consider Michael to be the only archangel. Raphael—mentioned in the deuterocanonical Book of Tobit—is also recognized in the Catholic and Orthodox churches. Gabriel, Michael, and Raphael are venerated in the Roman Catholic Church with a feast on September 29 (between 1921 and 1969, March 24 for Gabriel and October 24 for Raphael), and in the Eastern Orthodox Church on November 8 (if the Julian calendar is used, this corresponds to November 21 in the Gregorian). The named archangels in Islam are Gabriel, Michael, Israfil and Azrael. Jewish literature, such as the Book of Enoch, mentions Metatron as an archangel, called the "highest of the angels", though the acceptance of this angel is not canonical in all branches of the faith.

You see this is the problem with mythology. There are numerous variations you can choose from. You don't have to pick a specific one and declare that one as the supreme variation.

" Angels also have no free will"

What? Then explain how angels chose to leave Heaven  (which was a major part of the story of Noah) if they have no free will. And even in DxD Angels are bound by a system that will make them fall if they turn their backs on Heaven.

" and the Nephilim (such as what Akeno would be in the Bible) are giants"

How were the Nephilim even possible if angels don't have free will? Your own argument contradicts itself.

"Many have associated the Nephilim with giants. Giant traits may not have been limited to Nephilim alone: Goliath, a giant, was not considered Nephilim. As mentioned, the term Nephilim is unclear in definition. It is related to the verb “to fall” and the King James Version translates it as giants from the influence of the Latin Vulgate’s (early Latin translation by Jerome) term gigantes as well as the context from Numbers 13. The context of Genesis 6 does not reveal they were giants. There may have been some influence on the Latin Vulgate by the Septuagint’s (Greek translation of the Old Testament about 200–300 years before Christ) use of Greek word gigentes."

So the argument that Nephilims are giants is merely a "your own interpretation" thing. There were Giants in the bibles who weren't Nephilim and even the word doesn't translate to Giant. Even the biblical scriptures merely refer to them as "men of fame" so some of them could be freaks of nature Giants meanwhile others could merely be the size ordinary humans. And from a genetic aspect, there is no such thing as a absolute, for example, this is why in Harry Potter there can be squibs.

""Sitri is a demon associated with sexual vices, while Gaap is the one related to water."

This point is actually fair. I don't understand why in this case he couldn't just use Gaap. Maybe the Sitri gained water powers through marriage bonds with the Gaap clan and after their death they just keep the ability and became the water clan (similar to what the Gremory clan is doing with the Bael Clan). Hey! I just came up with a spin-off idea!!!

" I could say more, but this is enough, I believe, to show that Ishibumi does not abide letter for letter to actual mythology, and it's not a matter that you can resolve with saying "Angel gets a hobby after God dies". "

Literally only one out of all your examples was plausible, and even that could be given another explination (that wasn't disprove or proven in the dxd lore).

Also on the Sitri Clan page it states this: "Being the house that produced the current "Leviathan", members of the Sitri Clan have strong affinity for water-based magic, with the only known exception being Serafall Leviathan who excels in ice-based magic. "

Does this mean that they weren't always the water-based clan or that they merely took the title after another's clan untimely demise. Who knows? But again, I don't feel like searching the light novels for the quote and I can explain this away with a theory that is shown in canon (what the Gremory Clan did to Bael). So for the most part I can confidently say that Ishibumi doesn't completely contradict mythology.

Also regarding your little quip about Grendel: "Grendel is usually depicted as a monster or a giant, although his status is not clearly described in the poem and thus remains the subject of scholarly debate." Oh look, another open to debate, and not the same across all stories, scenario.

P.S. regarding my earlier comment, I wasn't trying to be rude but was merely making a joke
