There is an easy formula to determine how far you can see from a mountain top to a sea level area. Obviously the Earth's curvature is the limiting factor, and the higher we go, the farther we see.

D^2 + R^2 = (R + h)^2

In which
R = Earth's radius (6371 km)
D = Distance
h = Observer's height

As we need to find D, it becomes

D = (2hR + h^2)^0.5

If we want to know how far we can see from Mt Aconcagua to a sea level area (let's say the Pacific Ocean to the west), we have:

D = (2 * 6.960 * 6371 + 6.960^2) ^ 0.5
D = 298 km

So you can see up to 298 km to the west from the top of Mt Aconcagua. Beyond that, the sea stays below the horizon. Anyway, this is more than twice the distance between the mountain and the Chilean coast! Obviously these figures are approximate, as Earth's not a perfect sphere, the radius varies depending upon latitude/direction, plus refraction may play a role too.

However.... this formula applies for sea level places... if the focused object is another mountain top, it may be high enough to emerge from below the horizon, and this is what actually happens in many cases.

This link lists the longest sights possible from the Earth's surface: https://beyondhorizons.eu/lines-of-sight/

I think it is incomplete (and a bit messy), but surely provides the top sites.

It's a fact, Brazil is a country of low heights. Even this peak is located near the border with Venezuela, far away of every major or even middle-size city. The highest city is Campos do Jordão, 1,628 m high and about 2h far from São Paulo. The highest point which I visited is Mount Titlis, in Switzerland: 3,238 m (also the lower temperature which I experienced: -15°C)

Tolkien based his "elf language" on Finnish, and took inspiration from Scandinavian mythology, so why not?!

Haha I did both

Nice! I was just about to mention this. Curvature of the Earth affects on how far you can see surely so almost all initial examples given by the OP are nigh on impossible.

Colombia's highest points range from 17,500ft to 2 peaks both reaching 18,963ft. Various interesting things can be seen from a few:

1. Caribbean sea from the Santa Marta Sierra Nevada highest coastal mountains in the world...

There's a "half-way point" called the San Lorenzo crest where you can see the Caribbean sea on one side and the snowy peaks on the other.

3. Peru from some of the highest points in the Colombian Amazon, the table top mountains of Caquetá reaching over 3,200ft.

4. Also the Pacific Ocean and Ecuador can be seen from Southern Andean peaks.

It was partly based on Finnish, Estonian and Welsh, as well as some Old English.

Chimborazo

In Ecuador, it is the Chimborazo volcano/mountain with 6,263 m (20,548 ft) elevation, located in the Andes range (cordillera). The top completely covered by glaciers.
On clear days and with certain conditions, the summit can be seen from the coastal city of Guayaquil.
The summit of Mount Everest reaches a higher elevation above sea level, but the summit of Chimborazo is widely reported to be the farthest point on the surface from earth's center. (https://en.wikipedia.org/wiki/Chimborazo)
