I've been using 18mm on 35mm cameras for 35 or so years, I remember trying out the extremes and not being happy, only after I started using the wide as a complement and where it was suitable, did I start to fully understand how much I liked wide coverage.
The same thing with 4x5" cameras, I've been using a 65mm on 4x5" for 10-13 years. When we travel, for some reason the 65mm seems to be the correct lens for quite a few situations and it looks normal, not abnormal.
The seaside picture was taken about 3 weeks ago, I wished to take a picture that encompassed a holiday feeling. This was with the 65mm on my 4x5" camera, it is very wide, but you don't get a feeling that this is a very wide angle lens at work; but it is.
The fence remains in the Bronco Yard of an old outback station, does look slightly like a wide angle lens application, which it is, but it isn't screaming "I've used an ultra wide angle lens used here". At least I don't think it does; I took this 9 years ago.
The last image is a circular wheat silo in a rural town and yes, it is an architectural image, but it isn't screaming ultra wide angle; it looks reasonably normal.
I picked up a 24mm wide angle for 35mm photography in 1982 en route to Europe. Obviously I mostly used it in an urban/city environment, but was pleasantly surprised when more than a handful of landscape slides that looked very normal, as opposed to looking as though a wide(ish) lens was used.
It will take time, but eventually you'll arrive somewhere and realise that this is a subject suitable for your wide angle lens and you'll know how to implement the lens characteristics for the best outcome.
