Not technically an isekai but .hack//sign is great and basically about being trapped in a video game so it's similar.

Visions of Escaflowne is an isekai without the tropes, it's from the 90's and includes some mechas.

So I'm a Spider, So What? is good and I don't remember fan service or anything else being an issue.

I still enjoy Inuyasha and think it'd be worth you checking out if you haven't yet.

Ya Boy Kongming! is great, it's about a historic figure getting reincarnated in the modern world.

My Next Life as a Villainess, it's cheesy but I like it, villainess isekai has been gaining some steam in the last couple years.

Sonny Boy is amazing and definitely not your typical isekai.

Some favourite non-isekai but still worth checking out:

Jujutsu Kaisen
Fruits Basket 2019
Summer Time Rendering
Horimiya
Attack on Titan
Chainsaw Man
Kaguya-Sama: Love Is War

Lots of good recommendations already, I'll add some as well. Which should all be pretty much as non-fanservicey, loli, and misogyny free as isekai and fantasy anime get.
