The smallest reflector I like is a 130 f/5 reflector.
The AWB one sky is small and light weight because it collapses.
It is a table top dob. Meaning it works great if you have a sturdy table.
If you don't you will have to try one of many home grown options.
The 130 can also be mounted on any tripod mount that has a vixen saddle.
Such as the explore scientific twilight 1 mount.
For a refractor, I would get a astro-tec ed80. Same mount as above.
As far as reflector vs. refractor, a refractor is more efficient in getting light to the eyepiece.
Meaning a smaller refractor can compete with a larger reflector. An 80mm refractor
might be about the same as a 100mm reflector. The 130 reflector should be able
to present a better planetary image than the 80 frac.
refractors cool faster, and don't have the collimation issues that a reflector does.
In cold climates it is always ready to go.
the AT80 has a two inch focuser and can present a wider field of view than the
130 f/5 reflector, if you equip it with a 2 inch diagonal and 2 inch eyepiece.
Given your propensity for binoculars. I think I would go with the 80mm frac.
It is more binocular like than the reflector. Unless you feel like branching out.
