Any tsunami video I look at barely looks like a 20 feet wave hitting shore. But wikipedia tells me there have been dozens of 100+ feet tsunamis even in the last 10 years.

When they say 100 feet, it means that the wave reached 100 feet above sea level. This usually is at the point that the water loses all momentum(when everything is in gravitational potential energy), not when most of its energy is in kinetic energy moving forward.

A tsunami is a very long wave, so although it might be very tall, that will be normally seen as a very gradual increase in water height. In the open ocean a tsunami is imperceptible to shipping. When it reaches shore the front of the wave slows down and gains height. The real danger is that rather than breaking, a tsunami will keep on coming until after the peak of the wave hits shore, which might be hundreds of metres. And then of course they retreat hundreds of metres back out to sea laden with all the stuff they’ve just smashed up.

There are different types of tsunamis, there are the regular ones where the sea pulls back and comes back at a much higher level, and there are mega tsunamis where there is a catastrophic landslide one one part of a sea and that triggers a massive wave 100’s of feet high, a large meteor impact could also cause a mega tsunami, but if that was to happen the tsunami is the least of the worries.
Lots of posts are close but your responses indicate you still have questions.
Think of a tsunami as rising sea levels rather than a wave. As if the sea level suddenly became 100 ft higher.
As far as I know, there have not been tsunamis in areas with really tall buildings near the shore. That’s probably why you’re not finding the types of photos you’re expecting. People in areas that experience tsunamis don’t build really tall buildings near the water. But if you have a house that’s 100 ft above sea level facing the ocean, a tsunami would make it beach front property briefly (along with a tremendous amount of debris).
