Modpacks that prevent people from rushing to the end/nether.

Hey guys, I'm gonna be starting a server with a few people sometime in the next few days.
And was wondering if you guys have any recommendations for modpacks that would flat out prevent people from bumrushing to the end, because it's killed practically most survival servers I've tried to play on for more than a week.

I don't wanna pay for a server if it's gonna be dead after a week.
Looking for something rather challenging/difficult, but not being difficult just for the sake of it (Looking at you RL Craft lol) and preferably something fantasy-based (I rather dislike techpacks, played a lot of them over the past decade and they use a lot of the same mods).

If anybody could help, it'd be much appreciated.

Edit:
Some clarfications on what I'm looking for. Putting it plainly here for some peeps that didn't see it, so they can more clearly. because some people here didn't read my entire post.

- Only modpacks that are version 1.19.4 & up.

- No regular/insanely grindy tech modpacks, I find them boring.

- Fantasy/Rpg modpacks are heavily preferred

- Keep the comments relevant, to my question. if it's not in reply to this post or someone contributing a suggestion to this post. I politely ask that you please take it to pm's.

- No mod suggestions, I know there are mods that do this. But I'd rather have a better pack maker than I who's done it in a more natural way. Rather than just making progression halt all of a sudden.

- Please read the entire post before commenting, I tend to not enjoy repeating myself when asking for help.
I appreciate your responses though.
