Given you want the equivalent of three stations, and a U shape, OO is going to be cramped, except with very simple track plans of limited capacity, or by using unorthodox tricks..
OO9 keeps you in 4mm scale, and while there is much less choice available for locos and stock this is increasing quite quickly via 3D printing.
N allows more space, something akin to the 009 track plan, but has lots of variety of locos and stock and more choice of eras to opt for.
(my local narrow gauge railway has at least two locos at least 100 years old... will suit most eras!)
It is not necessarily smaller than OO9 as although the scale is smaller it represents models of much bigger engines and coaches.
Those are probably your main choices, though there are many different track plan ideas for each.
On place online to see how much variety exists even for small space layouts, and just for sheer amazement,
The late Carl Arendt collected an amazing collection of plans and built model railways for unusual and tiny locations.
Another good idea, if you've not done so already, is to visit a few local model railway exhibitions, to see what can be done in a variety of scales and spaces.
I found this while looking for a good picture to compare OO with OO9
A (very small) standard gauge loco and and a narrow gauge one to the same scale.
It's from this remarkable layout:http://gilesfavell.com/The%20Loop.htm
This actually O scale, in a space just 4ft by 2ft (plus fiddle yard), but the relative proportions remain the same for OO and OO9
