Phalaenopsis are the first choice since they are available and low light. Your size limits rules out most but there are many miniature and semi-miniature you can chose. Phal pulcherrima comes in several varieties and blooming this time of year.
Lady slippers take very low light and have that exotic look about them Literally thousands of varieties from which to chose.
Most orchids will grow in a room temperature but light is an issue for flowering.
Most orchids need a certain light level to initiate flowering. Lady slippers 900 foot candles, Phalaenopsis 1500, which is easy indoors, then Oncidium which are much larger than your desired range at 2500 fc, Dendrobium and Cattleya at 3500
Vanda are not appropriate for you except for Rhyncostylis gigantia which grows like a Phalaenopsis, stays reasonably sized and grows in a pot.
You sound like you intend to grow these cool. Most will handle it fine. In addition you can select some of the cooler growing orchids like Miltonia (pansy orchids) or Masdevallia. Zygopedilum are very fragrant and like cooler temps (50-80 degrees for all of these)
I have photos of all these in groups you could browse at
