As you have correctly pointed out, N-scale is great if space limitations don’t allow you to adequately run larger scales. Since it’s about 1/2 the size of HO-scale, you can get nearly twice as much bang for your buck with N-scale. And, as Ulrich points out, you are more limited with variety of items available in N-scale, although that has been improving over the past 10 years or so.
If you are wanting to try N-scale - go for it! There should be plenty of diesels available to pick from. Steam, OTOH, is a whole different matter. If you are interested in steam, stick with HO because you are VERY limited with the amount of choices on the market.
FWIW, HO is a great fit for me. Even if I had an abundance of space to run larger scales like S or O, I’d probably stick with HO because:
I could run/model more in the same amount of space
I’m comfortable with the scale and the “smallness” of parts
The amount of detailing is still terrific
I model steam/early diesel and would loose a lot of my roster because of lack of available models
Lastly, if sound is a big thing to you, trainluver, anything below HO-scale offers diminishing returns because you can’t fight physics when it comes to speaker size.
I ran HO for a number of years, I’m now building an N scale layout. I have a room approximately 10x13 in size. I wanted a roundhouse, a sizable yard, and a double track main line. These would be tough goals to meet in HO. I also wanted to have more scenery than I would if I went HO.
Although HO certainly offers a greater selection of rolling stock and motive power, I feel it just gives me an opportunity to scratch build more models. I’m also an “on again/off again” sail model ship builder, so the relative size of N scale was not a problem for me.
I model in HOj (1:80 scale, 16.5mm gauge) because, at the time I started modeling Japanese prototype, it was that or scratchbuild. Since all the available plans were also 1:80 scale…
Today, I enjoy the best of all possible worlds. My HOj freight cars are about as long as US prototype freight cars in N scale, locomotives are small, a prototypically-long freight train might be 8 feet long, my 24 inch radius curves look generous…
At the same time, things are big enough that my age-impaired vision and arthritic hands have no problem with them.
I have seen beautiful work done in N scale, and there’s no reason why an N scale empire shouldn’t be just as satisfying as its larger-scale equivalent. It’s a personal choice, not truly subject to rational argument - and better not left to a committee!

For me it was a 1’x6’ HO switching layout or a 1x6’ N Scale layout and since I been dabbling in N I switch my primary scale from HO to N so I could have a nice ISL.
Of course I modeled in N Scale during the 80s and once again started dabbling in N in 95 and built a N Scale ISL in 2003 and I suppose that was the slow beginning of the end for HO.
I sold 70% of my HO to fund my N Scale…
Now I dabble in HO at the club…
Another plus for me is there is a lot of modeling that still needs to be done in N…
One of my favorite N scale kit bashes.Landstar Elevators is 15 1/2" long.
