An airship would be something in between. They can be spacious enough for moving around inside while traveling and you can easily make stops at sightseeing destinations (airplanes use most fuel for starting, while that is essentially free with airships).
Time critical business travel would be probably not possible to replace, but as the pandemic has shown, those can be mostly replaced with online meetings anyways.
Honestly, 125km/h sounds like plenty. This monsters can travel in a straight line, so combined with good rail networks they should be more than enough for common travelling
Compared to what? Around 200 km/h was the top speed of the old ones in the 1930ties.
Now compare that to an airplane that can easily go x4 that.
Sure, but compare that to a cruise ship (which is the fairer comparison) which goes 4x less fast.
People don’t use cruise ships to travel. They use them for vacationing.(like a floating hotel)

No way, the maximum was around 100 kmh for most of them.
Source? They usually had a cruising speed around 125km/h.
