There are Minecraft mods that allow you to accomplish whatever you like including adding trains to making combat more akin to Elden Ring. Some mods are more subtle and are more focused on modifying the player's experience in subtle ways. Like the Minecraft Distant Horizons mod that lets you see forever.
Distant Horizons: The Level of Detail is a mod that expands the distance you can see. While it may sound simple but the result is that you'll be able see further than you normally. https://a1cdn.net/ Because the view from the summit of a mountain is breathtaking, every trip up a mountain's side becomes more significant.
It also makes it far easier to spot biomes you might be searching for. You can see things better from a distance, so you can find an angle that allows you to find the exact thing you're searching for. In case you were in need of additional proof of how much that can change things, TheMindIsStrange over on Reddit posted a few pictures to show off the mod, including the video below.

As you can see, it's incredible how much more rendering distance can add. They fly over a small part of the world and the sheer scale is huge. They also have a link to an image of how the End appears when this mod is enabled. It also shows how bizarre super flat universes could appear.
