Abrams stated in more than one interview that he didn't know Star Trek much beyond Wrath of Khan and wasn't much interested in Star Trek. Star Trek to JJ was always just the audition for Star Wars.

He proved he was great at nailing the aesthetic even if so many other qualities of the franchise like writing and plot take a back seat.

That's basically his Star Wars movies in a nutshell too: he absolutely nails the aesthetic 100% and everything else suffers. I think that's why they feel so much like fan service rather than standalone efforts because of that uncanny valley effect where they feel so much like old Star Wars movies and don't have great ideas but to ape old Star Wars plots, but still aren't "Old Star Wars". A lot of what was new in the films added greatly to the aesthetic of the franchise and pushed that, at least, in new directions.

Honestly, I think "the Emperor has returned somehow" is pure 100% Star Wars aesthetic, too. Weird cloning nonsense: very Star Wars. Evil villains returning at surprise hours after being silently behind the curtain for movies: very Star Wars. Absolutely the writing could have done better of foreshadowing that than by doing it in Fortnite of all places (!), but it's still very Star Wars to just "oh, here's the Emperor now". The new trilogy "rhymes" with the original trilogy: Snoke like Vader is clearly a Lieutenant of someone else (and turning out to be a broken clone of the Emperor, very Star Wars) and then Vader/Snoke are revealed to be less important and we fight the Emperor directly. The only missing is the "I am your father" bit for Snoke, but we all know how corny Rian Johnson thought that was, despite being the exact sort of soap opera (well, pulp serial) plotting that made Star Wars what it was/is.
