low ceilings have some intrinsic advantages, cheaper, and more efficient (less volume to HVAC), and they can feel very comfortable or 'cozy'
I agree, lighting design is much more critical with a low ceiling, or the room can look 'cave like', and it has to be integrated/consistent/even distributed, I would avoid hanging or surface fixtures, make it flush or low profile
also, imo you want large openings, the entrance ways from other rooms should be wide and no doors (bedrooms obviously excepted), to open it up. make it feel less constricted
glass/windows, lots of it, floor to ceiling is nice, maybe a whole wall
my main room clgs are 8'', but it has 3 large openings (~6'W x 7' H, main entry, kitchen, backyard) and 1 long wall 70% glass, 1 short ~50%, all lighting is recess except for 1 fixture over a table
